The First Amendment to the U.S. Constitution is only 45 words long, yet it protects our most basic freedoms. It reads in full:
"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
>*“But, above all else, the First Amendment means that government has no power to restrict expression because of its message, its ideas, its subject matter, or its content.”<br/><br />
—Supreme Court Justice Thurgood Marshall, Police Department of Chicago v. Mosley (1972)*

# 作用
> 用来匹配符合某种规则的字符串 , **字符串匹配**
>
> 是一个对象
# 创建
## 字面量方式创建
```js
let reg = /+86\d{11}/g
```
## 构造函数方式创建
麻烦，但正则规则可通过字符串拼接，有些场景不得不用
```js
let reg = new RegExp('+86\d{11}','g')
```
## 修饰符
| 修饰符 | 含义 |
| ------ | ---------- |
| g | 全局搜索 |
| i | 忽略大小写 |
| m | 多行搜索 |
# 常用方法
## test()
作用: 检查字符串是否符合正则对象的规则
```js
let reg = /+86\d{11}/g
reg.test(`+863i2794723`)
```
## 字符串的方法
> 正则对象作为字符串方法的参数 , 对字符串进行验证
| 方法 | 说明 |
| -------------------- | ------------------------------------ |
| search(reg) | 判断字符串是否匹配 |
| match(reg) | 返回一个数组 ， 里面放着匹配的字符串 |
| replace（reg , str） | 用str 替换掉匹配规则的字符串 |
| split(reg) | 返回一个数组 , 里面放着字符串切片 |
# 专用字符
| 字符 | 含义 |
| ------ | ----------------------------------------------------- |
| . | 匹配除了空格和回车的任意字符 <==>`[^\r\n]` |
| /xxxx/ | 字符匹配 |
| [xxx] | 范围匹配 : 匹配范围内的一个字符 [0-9] or [a-zA-Z] |
| [^] | 不是 ==> 取反 |
| \d | 匹配一个数字字符 <==> [0-9] |
| \D | <==> `[^0-9]` |
| \s | 匹配一个空格 |
| \S | 匹配非空格 |
| \w | <==> [a-zA-Z_0-9] |
# 量词
> 匹配多个字符
| 量词 | 作用 |
| ----- | ------------------------------------------ |
| ? | 前面的字符出现0次或者1次 ==>有没有都可以 |
| + | 前的字符 : 必须有 , 有多少次无所谓 |
| * | 前面的字符 : 0次 or n次 |
| {n} | 前面的字符出现n次 |
| {n,m} | q前面的字符出现n到m次 |
| {n,} | 至少出现n次 |
| | |
# 边界区分
> 以 xxx 开头 或者 以xxx结尾
| 正则 | 含义 |
| --------- | ----------------- |
| /^xxx/ | 以xxx开头 |
| /xxx$/ | 以xxx结尾 |
| /\bxxx\b/ | 匹配是单词的xxx |
| /\Bxxx\B/ | 匹配不是单词的xxx |
| | |
| | |
| | |
# 常用正则
## 匹配手机号
```js
let reg = /^1\d{10}$/
```
## 匹配邮箱
```js
let reg=/^[^@\s]+@[^@\s]+\.[^@\s]+$/
```
## 匹配用户名
```js
```
# 贪婪模式和非贪婪模式
> 默认是贪婪模式
>
> 在量词情况下{n.m} , 究竟选n匹配还是选m匹配??
>
> 默认是选m匹配 ,
{n,m}? 开启非贪婪模式 , 选n匹配
```js
let s = '123456789'
s.match(/\d{3,5}/g)
s.match(/\d{3,5}?/g)
```
## 实用举例
```js
`aa"helloworld"ok"jirengu"`.match(/".+"/g)
```
> 贪婪
会尽可能匹配 , 得到一个数组
`[""helloworld"ok"jirengu""]`
这不是我们希望的 , 我们希望得到["helloworld", "jirengu"]
> 非贪婪
```js
`aa"helloworld"ok"jirengu"`.match(/".+?"/g)
```
`["helloworld", "jirengu"]`
# 分组
```js
(xxx){3}
```
(xx) 被这些字符看撑一个整体去匹配
$n 来引用!!
# 前瞻
格式:
```js
exp1(?=exp2) 匹配后面是exp2的exp1
exp1(?exp2) 匹配后面不是exp2的 exp1
```
如:
```js
/hello(?=jirengu)/.test('hellojirengu') //true

# 前言
> 在繁杂的世界，能够沉下心来，梳理下知识体系，其实是一件很放松的诗意。
# 使用案例
1. 生产者发送消息方式：
1. 同步发送
2. 异步发送
3. 单向发送
4. 具体案例可以参考rocketmq源码的案例
2. 消费者接收消息方式：
1. 推
2. 拉
3. 实现顺序消息
1. 生产者
2. 消费者
3. 案例请查看rocketmq的源码中的example
4. RocketMQ保证的是消息的局部有序，而不是全局有序。要保证最终消费到的消息是有序的，需要从Producer、Broker、Consumer三个步骤都保证消息有序才行。
1. 首先在发送者端：在默认情况下，消息发送者会采取Round Robin轮询方式把消息发送到不同的MessageQueue(分区队列)，而消费者消费的时候也从多个MessageQueue上拉取消息，这种情况下消息是不能保证顺序的。而只有当一组有序的消息发送到同一个MessageQueue上时，才能利用MessageQueue先进先出的特性保证这一组消息有序。而Broker中一个队列内的消息是可以保证有序的。
2. 然后在消费者端：消费者会从多个消息队列上去拿消息。这时虽然每个消息队列上的消息是有序的，但是多个队列之间的消息仍然是乱序的。消费者端要保证消息有序，就需要按队列一个一个来取消息，即取完一个队列的消息后，再去取下一个队列的消息。而给consumer注入的MessageListenerOrderly对象，在RocketMQ内部就会通过锁队列的方式保证消息是一个一个队列来取的。MessageListenerConcurrently这个消息监听器则不会锁队列，每次都是从多个Message中取一批数据（默认不超过32条）。因此也无法保证消息有序。
4. 广播消息
1. 广播消息并没有特定的消息消费者样例，这是因为这涉及到消费者的集群消费模式。在集群状态(MessageModel.CLUSTERING)下，每一条消息只会被同一个消费者组中的一个实例消费到(这跟kafka和rabbitMQ的集群模式是一样的)。而广播模式则是把消息发给了所有订阅了对应主题的消费者，而不管消费者是不是同一个消费者组。
5. 延迟消息
1. 延迟消息实现的效果就是在调用producer.send方法后，消息并不会立即发送出去，而是会等一段时间再发送出去。这是RocketMQ特有的一个功能。
2. 那会延迟多久呢？延迟时间的设置就是在Message消息对象上设置一个延迟级别message.setDelayTimeLevel(3);
6. 批量消息
1. 批量消息是指将多条消息合并成一个批量消息，一次发送出去。这样的好处是可以减少网络IO，提升吞吐量。
2. 测试代码中都看到了关键的注释：如果批量消息大于1MB就不要用一个批次发送，而要拆分成多个批次消息发送。也就是说，一个批次消息的大小不要超过1MB
3. 批量消息的使用是有一定限制的，这些消息应该有相同的Topic，相同的waitStoreMsgOK。而且不能是延迟消息、事务消息等
7. 过滤消息
1. 在大多数情况下，可以使用Message的Tag属性来简单快速的过滤信息。
2. 主要是看消息消费者。consumer.subscribe("TagFilterTest", "TagA || TagC"); 这句只订阅TagA和TagC的消息。
3. TAG是RocketMQ中特有的一个消息属性。RocketMQ的最佳实践中就建议，使用RocketMQ时，一个应用可以就用一个Topic，而应用中的不同业务就用TAG来区分。
4. 但是，这种方式有一个很大的限制，就是一个消息只能有一个TAG，这在一些比较复杂的场景就有点不足了。这时候，可以使用SQL表达式来对消息进行过滤。
8. 事务消息
1. 之前有个博客里面写到了柔性分布式事务中的一个实现方案，就需要mq的消息确认机制，也就是这里描述的事务消息
2. 事务消息不支持延迟消息和批量消息。
3. 为了避免单个消息被检查太多次而导致半队列消息累积，我们默认将单个消息的检查次数限制为15 次，但是用户可以通过 Broker 配置文件的 transactionCheckMax 参数来修改此限制。如果已经检查某条消息超过 N 次的话（ N = transactionCheckMax ） 则 Broker 将丢弃此消息，并在默认情况下同时打印错误日志。用户可以通过重写 AbstractTransactionCheckListener 类来修改这个行为。
4. 事务消息将在 Broker 配置文件中的参数 transactionMsgTimeout 这样的特定时间长度之后被检查。当发送事务消息时，用户还可以通过设置用户属性 CHECK_IMMUNITY_TIME_IN_SECONDS 来改变这个限制，该参数优先于 transactionMsgTimeout 参数。
5. 事务性消息可能不止一次被检查或消费。
6. 提交给用户的目标主题消息可能会失败，目前这依日志的记录而定。它的高可用性通过RocketMQ 本身的高可用性机制来保证，如果希望确保事务消息不丢失、并且事务完整性得到保证，建议使用同步的双重写入机制。
7. 事务消息的生产者 ID 不能与其他类型消息的生产者 ID 共享。与其他类型的消息不同，事务消息
允许反向查询、MQ服务器能通过它们的生产者 ID 查询到消费者。
8. 事务消息机制的关键是在发送消息时，会将消息转为一个half半消息，并存入RocketMQ内部的一个RMQ_SYS_TRANS_HALF_TOPIC 这个Topic，这样对消费者是不可见的。再经过一系列事务检查通过后，再将消息转存到目标Topic，这样对消费者就可见了。
9. acl权限
1. 权限控制（ACL）主要为RocketMQ提供Topic资源级别的用户访问控制。用户在使用RocketMQ权限控制时，可以在Client客户端通过 RPCHook注入AccessKey和SecretKey签名；同时，将对应的权限控制属性（包括Topic访问权限、IP白名单和AccessKey和SecretKey签名等）设置在$ROCKETMQ_HOME/conf/plain_acl.yml的配置文件中。Broker端对AccessKey所拥有的权限进行校验，校验不过，抛出异常；
2. Broker端具体的配置信息可以参见源码包下docs/cn/acl/user_guide.md。主要是在broker.conf中打开acl的标志：aclEnable=true。然后就可以用plain_acl.yml来进行权限配置了。并且这个配置文件是热加载的，也就是说要修改配置时，只要修改配置文件就可以了，不用重启Broker服务。
# 源码探究
## Name Server
1. NameServer的核心作用其实就只有两个
1. 一是维护Broker的服务地址并进行及时的更新。
2. 二是给Producer和Consumer提供服务获取Broker列表。
### 源码
1. 从这里入口开始org.apache.rocketmq.namesrv.NamesrvStartup#main0
2. 主要是下面两行代码
```
NamesrvController controller = createNamesrvController(args);
start(controller);
```
3. org.apache.rocketmq.namesrv.NamesrvStartup#createNamesrvController 这个方法主要解析了命令行参数，且解析了配置，放在两个参数中：NameSrvConfig包含NameServer自身运行的参数，NettyServerConfig 包含Netty服务端的配置参数，Netty服务端口默认指定了9876。
4. 解析完毕参数后，实例化了对象NamesrvController
5. 接下来看看start方法：
```
public static NamesrvController start(final NamesrvController controller) throws Exception {
if (null == controller) {
throw new IllegalArgumentException("NamesrvController is null");
}
//初始化，主要是初始化几个定时任务
boolean initResult = controller.initialize();
if (!initResult) {
controller.shutdown();
System.exit(-3);
}
Runtime.getRuntime().addShutdownHook(new ShutdownHookThread(log, new Callable<Void>() {
@Override
public Void call() throws Exception {
controller.shutdown();
return null;
}
}));
controller.start();
return controller;
}
```
```
public boolean initialize() {
//加载KV配置
this.kvConfigManager.load();
//创建NettyServer网络处理对象
this.remotingServer = new NettyRemotingServer(this.nettyServerConfig, this.brokerHousekeepingService);
//Netty服务器的工作线程池
this.remotingExecutor =
Executors.newFixedThreadPool(nettyServerConfig.getServerWorkerThreads(), new ThreadFactoryImpl("RemotingExecutorThread_"));
//注册Processor，把remotingExecutor注入到remotingServer中
this.registerProcessor();
//开启定时任务:每隔10s扫描一次Broker,移除不活跃的Broker
this.scheduledExecutorService.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
NamesrvController.this.routeInfoManager.scanNotActiveBroker();
}
}, 5, 10, TimeUnit.SECONDS);
//开启定时任务:每隔10min打印一次KV配置
this.scheduledExecutorService.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
NamesrvController.this.kvConfigManager.printAllPeriodically();
}
}, 1, 10, TimeUnit.MINUTES);
if (TlsSystemConfig.tlsMode != TlsMode.DISABLED) {
// Register a listener to reload SslContext
try {
fileWatchService = new FileWatchService(
new String[] {
TlsSystemConfig.tlsServerCertPath,
TlsSystemConfig.tlsServerKeyPath,
TlsSystemConfig.tlsServerTrustCertPath
},
new FileWatchService.Listener() {
boolean certChanged, keyChanged = false;
@Override
public void onChanged(String path) {
if (path.equals(TlsSystemConfig.tlsServerTrustCertPath)) {
log.info("The trust certificate changed, reload the ssl context");
reloadServerSslContext();
}
if (path.equals(TlsSystemConfig.tlsServerCertPath)) {
certChanged = true;
}
if (path.equals(TlsSystemConfig.tlsServerKeyPath)) {
keyChanged = true;
}
if (certChanged && keyChanged) {
log.info("The certificate and private key changed, reload the ssl context");
certChanged = keyChanged = false;
reloadServerSslContext();
}
}
private void reloadServerSslContext() {
((NettyRemotingServer) remotingServer).loadSslContext();
}
});
} catch (Exception e) {
log.warn("FileWatchService created error, can't load the certificate dynamically");
}
}
return true;
}
```
```
public void start() throws Exception {
this.remotingServer.start();
if (this.fileWatchService != null) {
this.fileWatchService.start();
}
}
```
## broker启动
1. BrokerController.this.registerBrokerAll方法会发起向NameServer注册心跳。启动时会立即注册，同
时也会启动一个线程池，以10秒延迟，默认30秒的间隔 持续向NameServer发送心跳。
## producer
1. Producer需要拉取Broker列表，然后跟Broker建立连接等等很多
核心的流程，其实都是在发送消息时建立的。因为在启动时，还不知道要拉取哪个Topic的Broker列表
呢。
2. Producer在发送Netty请求时，实际上是指定的MessageQueue，而不是Topic。Topic只是用来找MessageQueue。然后根据MessageQueue再找所在的Broker，往Broker发送请求。
## 存储
消息存储的入口在：DefaultMessageStore.putMessage
1. commitLog写入
CommitLog的doAppend方法就是Broker写入消息的实际入口。这个方法最终会把消息追加到
MappedFile映射的一块内存里，并没有直接写入磁盘。写入消息的过程是串行的，一次只会允许一个
线程写入。
2. 分发ConsumeQueue和IndexFile
当CommitLog写入一条消息后，在DefaultMessageStore的start方法中，会启动一个后台线程
reputMessageService每隔1毫秒就会去拉取CommitLog中最新更新的一批消息，然后分别转发到
ComsumeQueue和IndexFile里去，这就是他底层的实现逻辑。
并且，如果服务异常宕机，会造成CommitLog和ConsumeQueue、IndexFile文件不一致，有消息写
入CommitLog后，没有分发到索引文件，这样消息就丢失了。DefaultMappedStore的load方法提供了
恢复索引文件的方法，入口在load方法。
3. 文件同步刷盘与异步刷盘
入口：CommitLog.putMessage -> CommitLog.handleDiskFlush
其中主要涉及到是否开启了对外内存。TransientStorePoolEnable。如果开启了堆外内存，会在启动
时申请一个跟CommitLog文件大小一致的堆外内存，这部分内存就可以确保不会被交换到虚拟内存
中。
4. 过期文件删除
入口： DefaultMessageStore.addScheduleTask ->
DefaultMessageStore.this.cleanFilesPeriodically()
默认情况下， Broker会启动后台线程，每60秒，检查CommitLog、ConsumeQueue文件。然后对
超过72小时的数据进行删除。也就是说，默认情况下， RocketMQ只会保存3天内的数据。这个时间可
以通过fileReservedTime来配置。注意他删除时，并不会检查消息是否被消费了。
整个文件存储的核心入口入口在DefaultMessageStore的start方法中。
5. 总结
1. RocketMQ的存储文件包括消息文件（Commitlog）、消息消费队列文件（ConsumerQueue）、Hash
索引文件（IndexFile）、监测点文件（checkPoint）、abort（关闭异常文件）。单个消息存储文件、
消息消费队列文件、Hash索引文件长度固定以便使用内存映射机制进行文件的读写操作。RocketMQ组
织文件以文件的起始偏移量来命令文件，这样根据偏移量能快速定位到真实的物理文件。
2. RocketMQ基于内存映射文件机制提供了同步刷盘和异步刷盘两种机制，异步刷盘是指在消息存储时先追加到内存映
射文件，然后启动专门的刷盘线程定时将内存中的文件数据刷写到磁盘。
3. CommitLog，消息存储文件，RocketMQ为了保证消息发送的高吞吐量，采用单一文件存储所有主题消
息，保证消息存储是完全的顺序写，但这样给文件读取带来了不便，为此RocketMQ为了方便消息消费
构建了消息消费队列文件，基于主题与队列进行组织，同时RocketMQ为消息实现了Hash索引，可以为
消息设置索引键，根据所以能够快速从CommitLog文件中检索消息。
4. 当消息达到CommitLog后，会通过ReputMessageService线程接近实时地将消息转发给消息消费队列
文件与索引文件。为了安全起见，RocketMQ引入abort文件，记录Broker的停机是否是正常关闭还是
异常关闭，在重启Broker时为了保证CommitLog文件，消息消费队列文件与Hash索引文件的正确性，
分别采用不同策略来恢复文件。
5. RocketMQ不会永久存储消息文件、消息消费队列文件，而是启动文件过期机制并在磁盘空间不足或者
默认凌晨4点删除过期文件，文件保存72小时并且在删除文件时并不会判断该消息文件上的消息是否被
消费。
## 消费者
1. 拉取消息。PullRequest里有messageQueue和processQueue，其中messageQueue负责拉取消息，拉取到后，
将消息存入processQueue，进行处理。 存入后就可以清空messageQueue，继续拉取了。
2. 在消费者示例的start方法中，启动RebalanceService，这个是客户端进行负载均衡策略的启动服务。他
只负责根据负载均衡策略获取当前客户端分配到的MessageQueue
3. 并发消费与顺序消费的过程。消费的过程依然是在DefaultMQPushConsumerImpl的 consumeMessageService中。他有两个子类
ConsumeMessageConcurrentlyService和ConsumeMessageOrderlyService。其中最主要的差别是ConsumeMessageOrderlyService会在消费前把队列锁起来，优先保证拉取同一个队列里的消息。消费过程的入口在DefaultMQPushConsumerImpl的pullMessage中定义的PullCallback中。
## 延迟消息
延迟消息的核心使用方法就是在Message中设定一个MessageDelayLevel参数，对应18个延迟级别。然
后Broker中会创建一个默认的Schedule_Topic主题，这个主题下有18个队列，对应18个延迟级别。消
息发过来之后，会先把消息存入Schedule_Topic主题中对应的队列。然后等延迟时间到了，再转发到目
标队列，推送给消费者进行消费。

#<a name="encrypting-your-content-with-storage-encryption-using-ams-rest-api"></a>Cifrar el contenido con el cifrado de almacenamiento con la API de REST de AMS
Se recomienda para cifrar el contenido localmente mediante el cifrado AES de 256 bits y luego cárguelo en el almacenamiento de Azure donde se almacenarán cifrados en el resto.
Este artículo proporciona una descripción general de cifrado de almacenamiento de AMS y muestra cómo cargar el contenido de almacenamiento cifrado:
- Crear una clave de contenido.
- Crear un activo. Establezca el AssetCreationOption en StorageEncryption cuando se crea el activo.
Cifrado activos tienen que estar asociadas con teclas de contenido.
- Vincular la clave de contenido activo.
- Establecer el cifrado de los parámetros en las entidades AssetFile relacionados.
>[AZURE.NOTE]Si desea ofrecer a un activo cifrado de almacenamiento, debe configurar Directiva de entrega del activo. Antes de que puedan transmitir su activo, el servidor de transmisión quita el cifrado de almacenamiento y transmite el contenido con la directiva de entrega especificado. Para obtener más información, vea [Configuración de directivas de entrega activos](media-services-rest-configure-asset-delivery-policy.md).
>[AZURE.NOTE] Cuando se trabaja con la API de REST de servicios de medios, se aplican las consideraciones siguientes:
>
>Al acceder a las entidades de Media Services, debe establecer los campos de encabezado específico y los valores en las solicitudes HTTP. Para obtener más información, consulte [configuración de desarrollo de API de REST de servicios de multimedia](media-services-rest-how-to-use.md).
>Después de conectarse correctamente a https://media.windows.net, recibirá una redirección 301 especificando otro URI de servicios de medios. Debe realizar las siguientes llamadas para el nuevo URI tal como se describe en [Conectar con Media Services con la API de REST](media-services-rest-connect-programmatically.md).
##<a name="storage-encryption-overview"></a>Introducción al cifrado de almacenamiento
El cifrado de almacenamiento AMS aplica el cifrado **AES CTR** modo a todo el archivo. Modo de CTR AES es un cifrado de bloques que puede cifrar datos de longitud arbitrario sin necesidad de relleno. Funciona mediante el cifrado de un bloque de contador con el algoritmo AES y luego xo-ión la salida de AES con los datos para cifrar o descifrar. El bloque de contador utilizado se construye copiando el valor de la InitializationVector en bytes 0 a 7 del valor contador y bytes 8 a 15 del valor contador están establecidos en cero. Del bloque de contador 16 bytes, bytes 8 a 15 (es decir, los bytes menos significativos) se utilizan como un entero simple de 64 bits que se incrementa en uno para cada bloque de datos subsiguientes procesa y se guarda en el orden de bytes de red. Tenga en cuenta que si este entero alcanza el valor máximo (0xFFFFFFFFFFFFFFFF) luego incrementar el restablecimiento del contador bloque a cero (bytes 8 a 15) sin afectar a los 64 bits del contador (es decir, bytes 0 a 7). Para mantener la seguridad de la AES CTR modo de cifrado, el valor de InitializationVector para un determinado identificador de clave para cada clave contenido deberá ser único para cada archivo y archivos será menor que 2 ^ 64 bloques de longitud. Esto es para asegurarse de que un valor de contador nunca se reutiliza con una clave determinada. Para obtener más información sobre el modo CTR, consulte [esta página wiki](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#CTR) (el artículo wiki utiliza el término "Valor de seguridad" en lugar de "InitializationVector").
Uso del **Cifrado de almacenamiento** para cifrar el contenido de borrar localmente mediante el cifrado AES de 256 bits y luego cárguelo en el almacenamiento de Azure donde esté almacenado cifrado al resto. Activos protegidos con cifrado de almacenamiento automáticamente sin cifrar y colocados en un sistema de archivos cifrados antes de codificación y, opcionalmente, cifrados de nuevo antes de cargarlo como un nuevo activo de salida. El caso de uso principal para el cifrado de almacenamiento es cuando desea proteger los archivos de medios de entrada de alta calidad con cifrado almacenados en disco.
Para poder ofrecer a un activo cifrado de almacenamiento, debe configurar Directiva de entrega del activo para que Media Services sepa cómo desea entregar el contenido. Antes de que puedan transmitir su activo, el servidor de transmisión quita el cifrado de almacenamiento y transmite el contenido con la directiva de entrega especificada (por ejemplo, AES, cifrado comunes o sin cifrado).
##<a name="create-contentkeys-used-for-encryption"></a>Crear ContentKeys utilizado para el cifrado
Cifrado activos tienen que estar asociadas a la clave de cifrado de almacenamiento. Debe crear la clave de contenido que se utilizará para el cifrado antes de crear los archivos de activos. Esta sección describe cómo crear una clave de contenido.
Los siguientes son los pasos generales para generar claves de contenido que se asociará con activos que desea cifrar.
1. Cifrado de almacenamiento aleatoriamente generar una clave AES de 32 bytes.
Se trata de la clave de contenido para su activo, lo que significa que todos los archivos asociados con ese activo tendrá que utilizar la misma clave de contenido durante el descifrado.
2. Llamar a los métodos [GetProtectionKeyId](https://msdn.microsoft.com/library/azure/jj683097.aspx#getprotectionkeyid) y [GetProtectionKey](https://msdn.microsoft.com/library/azure/jj683097.aspx#getprotectionkey) para obtener el certificado X.509 correcto que se debe usar para cifrar la clave de contenido.
3. Cifrar la clave de contenido con la clave pública del certificado X.509.
Media Services .NET SDK utiliza RSA con OAEP cuando se realiza el cifrado. Puede ver un ejemplo de .NET en la [función EncryptSymmetricKeyData](https://github.com/Azure/azure-sdk-for-media-services/blob/dev/src/net/Client/Common/Common.FileEncryption/EncryptionUtils.cs).
4. Crear un valor de suma de comprobación calculado utilizando el identificador de clave y la clave de contenido. En el siguiente ejemplo .NET calcula la suma de comprobación mediante el elemento GUID del identificador clave y la clave de borrar contenido.
public static string CalculateChecksum(byte[] contentKey, Guid keyId)
{
const int ChecksumLength = 8;
const int KeyIdLength = 16;
byte[] encryptedKeyId = null;
// Checksum is computed by AES-ECB encrypting the KID
// with the content key.
using (AesCryptoServiceProvider rijndael = new AesCryptoServiceProvider())
{
rijndael.Mode = CipherMode.ECB;
rijndael.Key = contentKey;
rijndael.Padding = PaddingMode.None;
ICryptoTransform encryptor = rijndael.CreateEncryptor();
encryptedKeyId = new byte[KeyIdLength];
encryptor.TransformBlock(keyId.ToByteArray(), 0, KeyIdLength, encryptedKeyId, 0);
}
byte[] retVal = new byte[ChecksumLength];
Array.Copy(encryptedKeyId, retVal, ChecksumLength);
return Convert.ToBase64String(retVal);
}
5. Crear la clave de contenido con **EncryptedContentKey** (que se convierten en cadena codificado base 64), **ProtectionKeyId**, **ProtectionKeyType**, **ContentKeyType**y **suma** los valores que ha recibido en los pasos anteriores.
Para el cifrado de almacenamiento, las siguientes propiedades deben incluirse en el cuerpo de la solicitud.
Solicitud de cuerpo (propiedad) | Descripción
---|---
Id. | El identificador de ContentKey que se genera nosotros con el siguiente formato, "nb:kid:UUID:<NEW GUID>".
ContentKeyType | Este es el tipo de clave de contenido como un número entero de esta clave de contenido. Se pasa el valor 1 para el cifrado de almacenamiento.
EncryptedContentKey | Crear un nuevo valor de clave contenido que es un valor de 256 bits (32 bytes). La clave se cifra utilizando el certificado X.509 cifrado de almacenamiento que se recupera desde Microsoft Azure Media Services mediante la ejecución de una solicitud HTTP GET para los métodos de GetProtectionKey y GetProtectionKeyId. Por ejemplo, vea el siguiente código .NET: el método **EncryptSymmetricKeyData** definido [aquí](https://github.com/Azure/azure-sdk-for-media-services/blob/dev/src/net/Client/Common/Common.FileEncryption/EncryptionUtils.cs).
ProtectionKeyId | Este es el identificador de clave de protección para el certificado X.509 cifrado de almacenamiento que se usó para cifrar la clave de contenido.
ProtectionKeyType | Este es el tipo de cifrado para la clave de protección que se usó para cifrar la clave de contenido. Este valor es StorageEncryption(1) en nuestro ejemplo.
Suma de comprobación |Suma de comprobación calculada MD5 para la clave de contenido. Se calcula mediante el cifrado el identificador de contenido con la clave de contenido. El código de ejemplo muestra cómo calcular la suma de comprobación.
###<a name="retrieve-the-protectionkeyid"></a>Recuperar el ProtectionKeyId

##<a name="create-an-assetfile"></a>Crear un AssetFile
La entidad [AssetFile](http://msdn.microsoft.com/library/azure/hh974275.aspx) representa un archivo de audio o vídeo que se almacena en un contenedor de blob. Un archivo de activos siempre está asociado a un activo y un recurso puede contener uno o varios archivos de activos. Se produce un error en la tarea de servicios de Media Encoder si un objeto de archivo activo no está asociado a un archivo digital en un contenedor de blob.
Tenga en cuenta que la instancia de **AssetFile** y el archivo multimedia reales son dos objetos. La instancia de AssetFile contiene metadatos acerca del archivo multimedia, mientras que el archivo multimedia contiene el contenido multimedia real.
Después de cargar el archivo de medios digitales en un contenedor de blob, usará la solicitud HTTP **Combinar** para actualizar la AssetFile con información sobre el archivo multimedia (no se muestra en este tema).

# Hello World! (when the document is ready)
You have to take the first steps in every frontend app:
* Connect `jQuery` - located in `bower_components` to the `index.html` file
* Connect `app.js` to the `index.html` file
* Alert a message, using `alert(message)`, when the document is ready!
In order to understand wether the document is ready or not, we can use:
```javascript
$(document).ready(someCallback);
```

# 6/18~6/24 の学習目標
## Progate で React の学習をする
## 6/18 ReactⅢ
1. コンポネートを作ろう
| 学習項目 | どんなことをやるか | わかったこと | 疑問 その他 |
| ----------------------- | -------------------------------------------------------- | --------------------------------------------------------------- | ---------------------- |
| 目標物を確認しよう | 制作物の完成形の確認 | 完成形を参考に組み立て方を考える | 訓練が必要 |
| ----------------------- | -------------------------------------------------------- | ------------ | ---------------------- |
| コンポネートを作成 | Lesson コンポネートの作成 | rendar メソッドの使い方 | 忘れたころに復習する |
| コンポネートの表示 1 個 | Lesson コンポネートを this.props を使って 1 個表示させる | </Lesson> 内で props 名 = props 値 を設定し this.props で渡し方 | |
| コンポネートの表示 複数 | map メソッドを使って 4 つのコンポネートを表示させる | map メソッドに上記を組み込んで複数のコンポネートを表示する方法 | |
## 6/19 ReactⅢ
1. モーダルの準備を使用しよう
| 学習項目 | どんなことをやるか | わかったこと | 疑問 その他 |
| ------------------ | ------------------------------------------------------------------------------------- | ------------ | ----------- |
| モーダルの JSX | introduction のコンポネートを作って props として渡す方法 | | |
| モーダルを隠そう 1 | state を false に定義してモーダルを隠す準備をする | | |
| モーダルの隠そう 2 | if 文を使って true の時のみ JSX が代入されるようにして false の時には表示させない方法 | | |
2. モーダルを完成させよう
| 学習項目 | どんなことをやるか | わかったこと | 疑問 その他 |
| ------------------------ | ------------------------------------------------------------------------------------------ | ------------ | ----------- |
| モーダルを表示しよう | handClick() を使ってクリックしたときに値を true にして JSX が代入されるようにする | | |
| モーダルを非表示にしよう | oneClick() を使って閉じるボタンをクリックしたときに値を false にしてモーダルを非表示にする | | |
## 6/20 ReactⅣ
1. 目標物の確認をしよう
| 学習項目 | どんなことをやるか | わかったこと | よくわからなかったこと |
| -------------------------- | ------------------------------------------ | ------------ | ---------------------- |
| お問い合わせフォームの確認 | 完成形から逆算して何をやるのかイメージする | | |
2. 送信完了メッセージを表示させよう
| 学習項目 | どんなことをやるか | わかったこと | よくわからなかったこと |
| ------------------------ | ---------------------------------------------------------------------------- | ------------ | ---------------------- |
| input と textra | 入力欄と送信ボタンを JSX で作る | | |
| 送信完了メッセージの作成 | if 文を使って送信前を false 送信後を true にして true の時のメッセージを作る | | |
| onSubmit と state の更新 | 送信ボタンが押されたときに値を true に変える処理をしてメッセージを表示させる | | |
3. 23 日以降の学習の準備
4. JSX とは何かを理解するにあたって
- React を React.createElement を使って書く部分を html のように記入することができる言語
- React.createElement は DOM でやった書き方に似ていた
- JSX は javascript に変換される、つまり JSX を入力するとそれが React.createElement に変換してから処理される
- JSX は React.createElement をシンプルに見やすく置き換えるもので使わなくても入力は可能ではある
## 6/21 ReactⅣ
1. 入力値を state で管理しよう
| 学習項目 | どんなことをやるか | わかったこと | よくわからなかったこと |
| ----------------------- | ------------------------------------------------------------- | ------------ | ---------------------- |
| 入力値の state 管理 | 入力値と state を紐づけしておく | | |
| onChange と入力値の習得 | oneCange イベントを使って入力したものを表示させる | | |
| state の更新 | メソッドを作って入力値を引数として受け取らせ state を更新する | | |
2. 入力チェックしよう
| 学習項目 | どんなことをやるか | わかったこと | よくわからなかったこと |
| ------------------------- | -------------------------------------------------------------------------- | ------------ | ------------------------------ |
| エラーメッセージの作成 | 入力値がからの時にエラーが表示される if 文を作る | | 定義の仕方がよくわからなかった |
| onChange と入力のチェック | 入力値がからかどうかを確認する条件文を作って true の時にエラーを表示させる | | |
## 6/22 ReactⅣ
1. チャレンジ問題に挑戦
| 学習項目 | どんなことをやるか | わかったこと | よくわからなかったこと |
| -------------- | ----------------------------------------------------- | ------------------------------------- | ------------------------------------------------------------ |
| チャレンジ問題 | ReactⅣ の内容を一通り通してお問い合わせフォームを作る | state の追加は`名前:初期値`で入力する | if 文の条件の this.state.state値 がどこで切り替わっているか |
2. ｚチャレンジ問題を通して全体をとおした復習と 23 日からの学習の準備
## 6/23-6/24 React.js & Next.js 超入門 3 コンポネート
1. 実際に入力して動きを確認する
2. 使い方を簡単にまとめ理解する
3. 利用したメソッドの名前使い方をリスト化しいつでも引き出せるようにする
4. これを 2 日行う
## 入力したこと やってみたことのポイント
- クラスの承継を使って作ったファイルを連動させる
- App.jsにコンポネートを作って画面に表示させる → うまくできなかった
## メソッドのリスト 6/23 更新無し
| メソッド名 | どう使うか | 気づいたこと その他 |

Control a chinese inverter On/Off/Reset switch with arduino nano, ethernet shield and Android app.
The "worker" controls the inverter with a relay contected to the pin `A0`.
Default "worker" IP `192.168.1.140` with MAC `90:A2:DA:0D:78:EE`.
The "sentinel" is optional and checks the status of the "worker". It also works as a physical remote to reset the "worker".
Default "sentinel" IP `192.168.1.141` with MAC `90:A2:DA:0D:78:EF`.
Example http request:
```http
http://192.168.1.140?s=1
```
Parameter `s` can be `0` (off) or `1` (on)
Note: You must be on the same network in order to work.

续 [上文](https://zhuanlan.zhihu.com/p/339033162)，对重复引用的各种方式作了更多测试，基于当前理解作一小结。
简言之，由于每次引用模块都对其执行（exec）一次，在多处引用同一模块的情况下，引用顺序和模块位置不同会导致不同结果。暂没想到此种行为的应用场景。
比如在 TypeDef 模块中定义一个类：
```
type Type1 { ; }
```
在同层目录下 Instance1 模块中声明一个个体：
```
using * in TypeDef
instance1 = Type1()
```
那么在另一模块中，先后引用 TypeDef 和 Instance1，如下的 isa 判断（对应 python 的 isinstance）返回 true，意料之中：
```
using * in TypeDef
using * in Instance1
print(isa(instance1, Type1))
```
但是以下的三种情况，全都返回 false：
- 情况 1：
```
using * in Instance1
using * in TypeDef
print(isa(instance1, Type1))
```
- 情况 2：
```
using TypeDef
using Instance1
print(isa(Instance1.instance1, TypeDef.Type1))
```
- 情况 3：
```
using Instance1
using TypeDef
print(isa(Instance1.instance1, TypeDef.Type1))
```
而如果 TypeDef 和 Instance1 在包内，行为又略有不同。如下返回 true（注意 TypeDef 在 Instance1 后引用）
```
using * in test.Instance1
using * in test.TypeDef
print(isa(instance1, Type1))
```
以下的三种情况，全都返回 false：
- 情况 4：
```
using * in test.TypeDef
using * in test.Instance1
print(isa(instance1, Type1))
```
- 情况 5：
```
using * in test.TypeDef
using test.Instance1
print(isa(test.Instance1.instance1, Type1))
```
- 情况 6：
```
using * in test.Instance1
using test.TypeDef
print(isa(instance1, test.TypeDef.Type1))
```
测试用例 [集结在此](https://gitee.com/MulanRevive/mulan-rework/tree/master/%E6%B5%8B%E8%AF%95/%E5%BC%95%E7%94%A8/isa)。
为规避，在应用中尽量保持“树式引用”，即一个模块只直接引用一次。

# REST简介
REST，全称是`Representational State Transfer`，译为表现层状态转化。REST并不是一个标准，而是一种软件架构风格。
在REST风格下，客户端通过url访问网络上的一个资源，通过HTTP动词请求服务端对资源进行操作。
# 接口版本
服务端接口是会不断变化更新的，一个好的设计，是提供不同版本的接口，而不是在一个接口上进行修改。部署时，服务端包含不同版本的接口，客户端可以依旧使用老版本的接口，也可以随服务端升级到新版本。当所有客户端都升级到新版本时，服务端可以考虑移除旧版本的接口。
在REST风格下，我们可以通过对接口增加版本号的概念，去区分不同版本的接口。版本号有两种表现形式，一种是包含在url中，一种是包含在HTTP头中。例如：
{% codeblock url %}
http://somewhere.com/xxx/v1/user
Accept: application/json; version=v1
{% endcodeblock %}
# Spring Boot starter源码
{% link 接口版本管理源码 https://github.com/it-linnan/api-version-spring-boot-starter %}
# 实现思路
Spring Boot提供了starter的标准，starter完成自动配置，开发者只需要引用starter，就可以实现功能。我们可以通过开发一个api-version-spring-boot-starter，帮助应用快速实现接口版本管理。
Spring Boot对于自定义starter提出的指导有以下几点：
1. 项目包含两个模块，一个是autoconfigure，一个是starter
2. autoconfigure模块包含自动配置相关的代码，和一个清单文件，清单文件中包含自动加载bean的class名
3. starter需引用autoconfigure模块和其他必要的依赖
因此，我们定义了两个模块，一个是autoconfigure，一个是starter，在autoconfigure中完成接口版本管理的功能和自动配置，实现在url中标明版本号。

## ApiVersion注解
首先，定义一个注解，注解的作用是标识controller的版本
{% codeblock ApiVersion.java lang:java %}
@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface ApiVersion {
/**
* 版本号
*
* @return 版本号
*/
@AliasFor("value")
String version() default "";
/**
* 版本号
*
* @return 版本号
*/
@AliasFor("version")
String value() default "";
}
{% endcodeblock %}
## 扩展RequestMappingHandlerMapping
`RequestMappingHandlerMapping`提供了url-controller方法间映射的能力，可以理解为在启动阶段，Spring扫描标注了`@Controller`注解的类，对其中标注了`@RequestMapping`注解的方法进行注册，key为`@RequestMaping`指定的url，value为方法。`@Controller`注解的变体有`@RestController`，`@RequestMapping`注解的变体有`@GetMapping`、`@PostMapping`等。当客户端发起请求时，`DispatcherServlet`在分发请求时，根据启动阶段注册的url和方法映射进行分发。
因此我们需要扩展两个类，一个是`RequestMappingHandlerMapping`，在注册url时，将url注册为统配符的形式，如`{version}/user`。另外一个是`RequestCondition`，提供具体的匹配规则。
具体工作原理是：
1. 服务端启动阶段，Spring扫描Controller，注册能力由`ApiVersionUrlRequestMappingHandlerMapping`提供，将标注了`@ApiVersion`注解的Controller，url统一注册为统配符的形式，形如`{version}/user`，同时将定义的版本号也作为url的属性，注册到Spring容器中
2. 客户端发起请求，请求的url形如`v1/user`
3. `DispathcerServlet`接受到请求，对请求的url与注册的url进行匹配。匹配规则由`ApiVersionUrlRequestCondition`提供，即注册url符合请求的url，且注册版本号与请求的版本号一致，即为匹配成功
{% codeblock ApiVersionUrlRequestCondition.java lang:java %}
@NoArgsConstructor
public class ApiVersionUrlRequestCondition implements RequestCondition<ApiVersionUrlRequestCondition>, ApplicationContextAware {
@Getter
private String version;
private static String regexFormat = "";
public ApiVersionUrlRequestCondition(String version) {
this.version = version;
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
if (regexFormat == null || regexFormat.length() == 0) {
ApiVersionProperties apiVersionProperties = applicationContext.getBean(ApiVersionProperties.class);
ServerProperties serverProperties = applicationContext.getBean(ServerProperties.class);
if (serverProperties.getServlet().getContextPath() != null) {
regexFormat = serverProperties.getServlet().getContextPath();
}
regexFormat += "/" + apiVersionProperties.getPrefix() + "%s/**";
}
}
@Override
public ApiVersionUrlRequestCondition combine(ApiVersionUrlRequestCondition other) {
return new ApiVersionUrlRequestCondition(other.getVersion());
}
@Override
public ApiVersionUrlRequestCondition getMatchingCondition(HttpServletRequest request) {
PathMatcher pathMatcher = new AntPathMatcher();
boolean match = pathMatcher.match(String.format(regexFormat, version), request.getRequestURI());
return match ? this : null;
}
@Override
public int compareTo(ApiVersionUrlRequestCondition other, HttpServletRequest request) {
return other.getVersion().compareTo(this.version);
}
}
{% endcodeblock %}
{% codeblock ApiVersionUrlRequestMappingHandlerMapping.java lang:java %}
@Slf4j
public class ApiVersionUrlRequestMappingHandlerMapping extends RequestMappingHandlerMapping {
public static final String VERSION_PREFIX = "/{version}";
public static final String PATH_KEY = "path";
public static final String VALUE_CACHE_KEY = "valueCache";
@Override
protected RequestCondition<ApiVersionUrlRequestCondition> getCustomTypeCondition(Class<?> handlerType) {
ApiVersion apiVersion = AnnotationUtils.findAnnotation(handlerType, ApiVersion.class);
return createCondition(apiVersion);
}
@Override
protected RequestCondition<ApiVersionUrlRequestCondition> getCustomMethodCondition(Method method) {
ApiVersion apiVersion = AnnotationUtils.findAnnotation(method, ApiVersion.class);
return createCondition(apiVersion);
}
@Override
protected RequestMappingInfo getMappingForMethod(Method method, Class<?> handlerType) {
RequestMappingInfo info = createRequestMappingInfo(method);
if (info != null) {
RequestMappingInfo typeInfo = createRequestMappingInfo(handlerType);
if (typeInfo != null) {
info = typeInfo.combine(info);
}
}
return info;
}
@Nullable
private RequestMappingInfo createRequestMappingInfo(AnnotatedElement element) {
RequestMapping requestMapping = AnnotatedElementUtils.findMergedAnnotation(element, RequestMapping.class);
ApiVersion apiVersion = AnnotationUtils.findAnnotation(element, ApiVersion.class);
if (apiVersion != null) {
InvocationHandler invocationHandler = Proxy.getInvocationHandler(requestMapping);
Class<? extends InvocationHandler> clazz = invocationHandler.getClass();
try {
Field declaredField = clazz.getDeclaredField(VALUE_CACHE_KEY);
declaredField.setAccessible(true);
Map<String, Object> valueCache = (Map) declaredField.get(invocationHandler);
String[] path = requestMapping.path();
if (path != null) {
for (int i = 0; i < path.length; i++) {
path[i] = VERSION_PREFIX + path[i];
}
valueCache.put(PATH_KEY, path);
declaredField.set(invocationHandler, valueCache);
}
} catch (NoSuchFieldException | IllegalAccessException e) {
log.error("这是不可能发生的事。。", e);
}
}
RequestCondition<?> condition = (element instanceof Class ?
getCustomTypeCondition((Class<?>) element) : getCustomMethodCondition((Method) element));
return (requestMapping != null ? createRequestMappingInfo(requestMapping, condition) : null);
}
private RequestCondition<ApiVersionUrlRequestCondition> createCondition(ApiVersion apiVersion) {
return apiVersion == null ? null : new ApiVersionUrlRequestCondition(apiVersion.version());
}
}
{% endcodeblock %}
## 配置RequestMappingHandlerMapping
自定义了`RequestMappingHandlerMapping`后，我们需要注册自定义处理类，让Spring容器使用自定义处理类进行url注册。注册自定义处理类的方法非常简单，只需要扩展`WebMvcRegistrations`，覆写`getRequestMappingHandlerMapping`方法即可。
{% codeblock ApiVersionUrlWebConfig.java lang:java %}
public class ApiVersionUrlWebConfig implements WebMvcRegistrations {
@Override
public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
return new ApiVersionUrlRequestMappingHandlerMapping();
}
}
{% endcodeblock %}
## 配置版本号前缀
考虑到有些人习惯将版本号定义为`v1`，有的人则习惯定义为`1`，我们还需要提供版本号前缀的配置项。
{% codeblock ApiVersionProperties.java lang:java %}
@Data
@ConfigurationProperties(prefix = "api.version")
public class ApiVersionProperties {
/**
* 全局版本号前缀
*/
private String prefix = "v";
}
{% endcodeblock %}
## 自动配置
Spring Boot starter的核心思想是自动配置，因此，我们需要注册以上所有的bean到Spring容器中。
### 自动配置类
{% codeblock ApiVersionHttpConfiguration.java lang:java %}
@Configuration
@EnableConfigurationProperties
@ConditionalOnWebApplication
public class ApiVersionHttpConfiguration {
@Bean
public ApiVersionUrlWebConfig apiVersionUrlWebConfig() {
return new ApiVersionUrlWebConfig();
}
@ConditionalOnMissingBean
@Bean
public ApiVersionProperties apiVersionProperties() {
return new ApiVersionProperties();
}
@ConditionalOnMissingBean
@Bean
public ApiVersionUrlRequestCondition apiVersionUrlRequestCondition() {
return new ApiVersionUrlRequestCondition();
}
}
{% endcodeblock %}
### 配置清单
Spring规定了清单文件的路径resources/META-IN/spring.factories，我们需要在清单文件中标注自动配置类的路径
{% codeblock spring.factories lang:properties %}
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
priv.ln.api.version.spring.boot.autoconfigure.ApiVersionHttpConfiguration
{% endcodeblock %}
# 在Spring Boot项目中使用接口版本管理
在pom.xml中添加依赖，引用starter。
在Controler中添加注解
{% codeblock lang:java %}
@ApiVersion("1")
@Controller
@RequestMapping("/xxx")
public class XxxController{
}
{% endcodeblock %}
访问该接口时，通过url`/v1/xxx`访问

'''--- Day 10: Balance Bots ---
You come upon a factory in which many robots are zooming around handing small microchips to each other.
Upon closer examination, you notice that each bot only proceeds when it has two microchips, and once it does, it gives each one to a different bot or puts it in a marked "output" bin. Sometimes, bots take microchips from "input" bins, too.
Inspecting one of the microchips, it seems like they each contain a single number; the bots must use some logic to decide what to do with each chip. You access the local control computer and download the bots' instructions (your puzzle input).
Some of the instructions specify that a specific-valued microchip should be given to a specific bot; the rest of the instructions indicate what a given bot should do with its lower-value or higher-value chip.
For example, consider the following instructions:
value 5 goes to bot 2
bot 2 gives low to bot 1 and high to bot 0
value 3 goes to bot 1
bot 1 gives low to output 1 and high to bot 0
bot 0 gives low to output 2 and high to output 0
value 2 goes to bot 2
Initially, bot 1 starts with a value-3 chip, and bot 2 starts with a value-2 chip and a value-5 chip.
Because bot 2 has two microchips, it gives its lower one (2) to bot 1 and its higher one (5) to bot 0.
Then, bot 1 has two microchips; it puts the value-2 chip in output 1 and gives the value-3 chip to bot 0.
Finally, bot 0 has two microchips; it puts the 3 in output 2 and the 5 in output 0.
In the end, output bin 0 contains a value-5 microchip, output bin 1 contains a value-2 microchip, and output bin 2 contains a value-3 microchip. In this configuration, bot number 2 is responsible for comparing value-5 microchips with value-2 microchips.
Based on your instructions, what is the number of the bot that is responsible for comparing value-61 microchips with value-17 microchips?
