How does this code works in c++? : <p>I participated in Codeforces Round #396 (Div. 2) yesterday.
The (A) problem seemed pretty advanced in my opinion when I read it.
I tried solving it all the competition time yesterday and some time today.
I came up with a 200 lines long(half-working) solution. And then I gave up.</p>
<p>I looked what other people wrote there and I saw max 20 lines long code that seems magic to me.</p>
<p>The problem asks you to output the length of the longest uncommon subsequence of letters from two strings.
You can read the full problem here:
<a href="http://codeforces.com/contest/766/problem/A" rel="nofollow noreferrer">http://codeforces.com/contest/766/problem/A</a></p>
<pre><code>#include<bits/stdc++.h>
using namespace std;
string a,b;
int main(){
cin>>a>>b;
printf("%d",a==b?-1:max(a.size(),b.size()));
return 0;
}
</code></pre>
<p>This is all the code used to solve the problem, and I really want to know how that one line of code</p>
<pre><code>printf("%d",a==b?-1:max(a.size(),b.size()));
</code></pre>
<p>can solve this "advanced" task?</p>

C# Post Increment : <p>While I am testing post increment operator in a simple console application, I realized that I did not understand full concept. It seems weird to me:</p>
<pre><code>int i = 0;
bool b = i++ == i;
Console.WriteLine(b);
</code></pre>
<p>The output has been false. I have expected that it would be true. AFAIK, at line 2, because of the post increment, compiler does comparison and assigned b to true, after i incremented by one. But obviously I am wrong.
After that I modify the code like that:</p>
<pre><code>int i = 0;
bool b = i == i++;
Console.WriteLine(b);
</code></pre>
<p>This time output has been true. What did change from first sample?</p>

Gitlab docker executor - cache image after before_script : <p>In <code>gitlab-ci</code> there's an option in the <a href="http://doc.gitlab.com/ce/ci/yaml/README.html" rel="noreferrer"><code>.gitlab-ci.yml</code></a> file to execute commands before any of the actual script runs, called <code>before_script</code>. <code>.gitlab-ci.yml</code> examples illustrate installing ancillary programs here. However, what I've noticed is that these changes are not cached in Docker when using a docker executor. I had naively assumed that after running these commands, docker would cache the image, so for the next run or test, docker would just load the cached image produced after <code>before_script</code>. This would drastically speed up builds.</p>
<p>As an example, my <code>.gitlab-ci.yml</code> looks a little like:</p>
<pre><code>image: ubuntu
before_script:
- apt-get update -qq && apt-get install -yqq make ...
build:
script:
- cd project && make
</code></pre>
<p>A possible solution is to go to the runner machine and create a docker image that can build my software without any other installation and then reference it in the <code>image</code> section of the yaml file. The downside of this is that whenever I want to add a dependency, I need to log in to the runner machine and update the image before builds will succeed. It would be much nicer if I just had to add the dependency to to the end of <code>apt-get install</code> and have docker / gitlab-ci handle the appropriate caching.</p>
<p>There is also a <code>cache</code> command in <code>.gitlab-ci.yml</code>, which I tried setting to <code>untracked: true</code>, which I thought would cache everything that wasn't a byproduct of my project, but it didn't seem to have any effect.</p>

Angular 5: remove route history : <p>In my app I have a category page that has links to a various product list pages. If it turns out that when you get to a product list page there is only one product then it automatically navigates to that product detail page. What I want is to remove the product list page route in the history so that when the user is on the product detail page and hits the back button they will go to the category page and not the product list page because that will just redirect them back to the detail page.</p>

How do I count by frequency of a letter in index in Pyhton : lets say youre giving 5 inputs like so:
hello
hullo
zeros
It is then stored into a list like so ['hello','hullo','zeros']
I would like it to return a dictionary that counts the frequency of the letter in their index.
It should return something like this
{h:2,z:1} {e:2,u:1} {l:2,r:1} {l:2,o:1} {o:2,s:1}

For some surveys I find the FETCH works OK but the GET is rejected with error 503. For instance:</p>
<p><code>HttpError 503 when requesting https://www.googleapis.com/consumersurveys/v2/surveys/6mndemyqw5b5k?alt=json returned "Survey is configured in a way not supported by the API, i.e. contains unsupported question types or options Request Id: 5750b15c00ff025d5da8b9f4b00001737e3430322d747269616c320001707573682d30362d30322d7231330001010a</code></p>
<p>The surveys are nearly all one single response questions and were created with the web interface. The common factor I notice is that the failing surveys I have looked at all contain an answer with a non-Latin character, e.g. <code>Siân Berry (Green)</code>.</p>
<p>Whatever the reason, this is quite a problem because the GET operation is the only one that returns a full list of answers in the originally specified order.
Also, the question text itself is only otherwise available by scraping the Overview sheet of the exported XLS file. I say scraping because so far as I can tell the spreadsheet format is neither documented nor stable - for instance the response data used to be in worksheet "1" but more recently seem to be in worksheet "Complete responses".</p>

How does numpy.reshape() with order = 'F' work? : <p>I thought I understood the reshape function in Numpy until I was messing around with it and came across this example:</p>
<pre><code>a = np.arange(16).reshape((4,4))
</code></pre>
<p>which returns:</p>
<pre><code>array([[ 0, 1, 2, 3],
[ 4, 5, 6, 7],
[ 8, 9, 10, 11],
[12, 13, 14, 15]])
</code></pre>
<p>This makes sense to me, but then when I do:</p>
<pre><code>a.reshape((2,8), order = 'F')
</code></pre>
<p>it returns:</p>
<pre><code>array([[0, 8, 1, 9, 2, 10, 3, 11],
[4, 12, 5, 13, 6, 14, 7, 15]])
</code></pre>
<p>I would expect it to return:</p>
<pre><code>array([[0, 4, 8, 12, 1, 5, 9, 13],
[2, 6, 10, 14, 3, 7, 11, 15]])

Move constant object without compiler warning : <p>I tested the following code using Visual Studio 2017 version 15.3.1. </p>
<p><code>v.push_back(std::move(str1))</code> works as expected. It moves the contents of <code>str1</code> into the vector.</p>
<p><code>str2</code> is a constant string. Since a constant string cannot be modified after it is created, I was expecting that the <code>v.push_back(std::move(str2))</code> statement would result in a compiler warning. However, to my surprise there was no compiler warning. After stepped into it, I found that the overload of <code>push_back(const T&)</code> was actually called. The <code>std::move</code> in <code>std::move(str2)</code> seems has no effect.</p>
<p>My question: Should a compiler warning be given for trying to move a constant object?</p>
<pre><code>// Compiled with Visual Studio 2017 version 15.3.1
std::vector<std::string> v;
std::string str1 = "string 1";
v.push_back(std::move(str1));
// Call push_back(T&&). The contents of str1 is moved into the vector.
// This is less expensive, but str1 is now valid but unspecified.
const std::string str2 = "string 2";
v.push_back(std::move(str2));
// Call push_back(const T&). A copy of str2 is added into the vector.
// str2 itself is unchanged.

ImageView/ImageButton overlay on camera preview not dislayed : A very standard overlay [tutorial][1] in this link was followed for developing the camera preview with overlay. However, when I change the `<Button/>` to `<ImageView/>` or `<ImageButton/>` the image doesn't get displayed. All I am getting is camera preview while using `<ImageView/>` and on using `<ImageButton/>` the images are not shown however little white lines at places where there should be images are displayed. The images are present in `mipmap-xxhdpi`. These buttons will be used to start another activity or take picture on click by user.
I've looked into many questions on StackOverFlow but solutions don't work for me. Answer [here][2] doesn't work for me.
**Other Relevant Details**
The minSdkVersion is 16 and compileSdkVersion is 25. When I run the app in emulator on API-21 or above all I am getting is a black screen.
***Q1:*** How to overlay `<ImageView/>` or `<ImageButton/>` on camera preview?
***Q2:*** Would getting black screen have something to do with Camera API (old) being deprecated and I have to build separate classes to take into account different API?
Like the code below
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
//do something
} else {
//do something else
}

In Ansible, how to combine variables from separate files into one array? : <p>In Ansible, in a role, I have vars files like this:</p>
<pre><code>vars/
app1.yml
app2.yml
</code></pre>
<p>Each file contains vars specific to an app/website like this:</p>
<pre><code>name: app1
git_repo: https://github.com/philgyford/app1.git
# ...
</code></pre>
<p>Ideally, without the task knowing in advance which apps have variable files, I'd like to end up with an array called <code>apps</code> like this:</p>
<pre><code>apps:
- name: app1
git_repo: https://github.com/philgyford/app1.git
# ...
- name: app2
git_repo: https://github.com/philgyford/app2.git
# ...
</code></pre>
<p>ie, that combines the variables from the files into one.</p>
<p>I know I can load all the variable files like this:</p>
<pre><code>- name: Load var files
with_fileglob:
- ../vars/*.yml
include_vars: '{{ item }}'
</code></pre>
<p>But given each file has identical variable names, it will overwrite each previous set of variables. I can't see a way to load the variables and put them into an <code>apps</code> array.</p>
<p>I'm open to rearranging things slightly if it's the only way to make something like this possible.</p>

AWS Cognito - User stuck in CONFIRMED and email_verified = false : <p>How do I go about email verifying a user who is CONFIRMED yet email_verified is false?</p>
<p>The scenario is roughly an agent signs up user on their behalf, and I confirm the user through the admin call adminConfirmSignUp. At that point, the user cannot change their password because of the email_verified flag being false.</p>
<p>I can't call resendConfirmationCode because the user is already confirmed.</p>
<p>I can't call forgotPassword because the email_verified flag is false.</p>
<p>The best I can think of is deleting the user account and calling signUp (prompting them to re-enter their password or a new password), hence recreating their account.</p>

How to print every third element od Array? : I have a problem. I need to take 2 inputs from user (size of array) and then second input (elements of that same array).
After that i need to print every third element of array.
I done it! But with this i can print elements from last element in array and i want to print from first.
Example size of array is 9.
Elements: 1,2,3,4,5,6,7,8,9.
I need to print 3,6,9 but i am printing 9,6,3 :D
Help,
Here is my code so far.
class Demo {
public static void main(String[] args) {
int x;
int[] y;
Scanner tastatura = new Scanner(System.in);
System.out.println("Enter size of array:");
x = tastatura.nextInt();
y = new int[x];
System.out.println("Enter the elements of array:");
for (int i = 0; i < x; i++) {
y[i] = tastatura.nextInt();
}
System.out.println("\n Every third element of array is : ");
for (int i = y.length - 1; i >= 0; i = i - 3) {
System.out.println(y[i]);
}

Dapper with .NET Core - injected SqlConnection lifetime/scope : <p>I'm using .NET Core Dependency Injection to instantiate a <code>SqlConnection</code> object during the application startup, which I'm then planning to inject in my repository. This <code>SqlConnection</code> will be used by Dapper to read/write data from the database within my repository implementation. I am going to use <code>async</code> calls with Dapper.</p>
<p>The question is: should I inject the <code>SqlConnection</code> as transient or as a singleton? Considering the fact that I want to use <code>async</code> my thought would be to use transient unless Dapper implements some isolation containers internally and my singleton's scope will still be wrapped within whatever the scope Dapper uses internally.</p>
<p>Are there any recommendations/best practices regarding the lifetime of the SqlConnection object when working with Dapper? Are there any caveats I might be missing?</p>
<p>Thanks in advance.</p>

Java Data Structures (Most Efficient Structure For Specific Program) : <p>Question from textbook exercise: </p>
<p>A hospital has a capacity of n patients. Each time a patient comes in he is assessed and, if in noncritical condition, has to wait his turn. If in critical condition, he is moved as the next to be treated. If a patient is in the washroom when called, he skips his turn and is treated as a new patient.
At any point in time, the hospital needs to know who is being treated, and what capacity there is left.</p>
<p>Would it be more efficient to solve this problem with (able to chose more than one answer):
1. deque
2. array
3. circuluar array
4. custom data structure: array + stack
5. stack</p>

Is it normal that transfer learning (VGG16) performs worse on CIFAR-10? : <p><strong>Note:</strong> I am not sure this is the right website to ask these kind of questions. Please tell me where I should ask them before downvoting this "because this isn't the right place to ask". Thanks!</p>
<p>I am currently experimenting with deep learning using <a href="https://keras.io" rel="nofollow noreferrer">Keras</a>. I tried already a model similar to the one to be found on <a href="https://keras.io/examples/cifar10_cnn/" rel="nofollow noreferrer">the Keras example</a>. This yields expecting results:</p>
<ul>
<li>80% after 10-15 epochs without data augmentation before overfitting around the 15th epoch and</li>
<li>80% after 50 epochs with data augmentation without any signs of overfitting.</li>
</ul>
<p>After this I wanted to try transfer learning. I did this by using the <a href="https://keras.io/applications/#vgg16" rel="nofollow noreferrer">VGG16</a> network without retraining its weights (see code below). This gave very poor results: 63% accuracy after 10 epochs with a very shallow curve (see picture below) which seems to be indicating that it will achieve acceptable results only (if ever) after a very long training time (I would expect 200-300 epochs before it reaches 80%).</p>
<p><a href="https://i.stack.imgur.com/MWmsT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MWmsT.png" alt="Transfer learning results"></a></p>
<p>Is this normal behavior for this kind of application? Here are a few things I could imagine to be the cause of these bad results:</p>
<ul>
<li>the CIFAR-10 dataset has images of <code>32x32</code> pixels, which might be too few for the VGG16 net</li>
<li>The filters of VGG16 are not good for CIFAR-10, which would be solved by setting the weights to <code>trainable</code> or by starting with random weights (only copying the model and not the weights)</li>
</ul>
<p>Thanks in advance!</p>

<p>And it's OK, as you see there is another option which you can upload files as form data(key, value):</p>
<p><a href="https://i.stack.imgur.com/V0Lbt.png" rel="noreferrer"><img src="https://i.stack.imgur.com/V0Lbt.png" alt="enter image description here"></a></p>
<p>Every tutorials (like <a href="https://futurestud.io/tutorials/retrofit-2-how-to-upload-files-to-server" rel="noreferrer">this one</a>)describe how to upload files as <code>multipart/form-data</code>:</p>
<pre><code> // create RequestBody instance from file
RequestBody requestFile =
RequestBody.create(MediaType.parse("multipart/form-data"), file);
// MultipartBody.Part is used to send also the actual file name
MultipartBody.Part body =
MultipartBody.Part.createFormData("picture", file.getName(), requestFile);
</code></pre>
<p>I search a lot but couldn't find any way to upload file as binary with retrofit2.</p>
<p>There is just one Issue in <strong>retrofit</strong> repository which ask <strong><a href="https://github.com/square/retrofit/issues/1217" rel="noreferrer">How can I POST a image binary in retrofit 2.0 beta?</a></strong>. I use its solution :</p>
<p>API Service:</p>
<pre><code>@POST("trip/{tripId}/media/photos")
Call<MediaPost> postEventPhoto(
@Path("eventId") int tripId,
@Header("Authorization") String accessToken,
@Query("direction") String direction,
@Body RequestBody photo);
</code></pre>
<p>Caller:</p>
<pre><code>InputStream in = new FileInputStream(new File(media.getPath()));
byte[] buf;
buf = new byte[in.available()];
while (in.read(buf) != -1);
RequestBody requestBody = RequestBody
.create(MediaType.parse("application/octet-stream"), buf);
Call<MediaPost> mediaPostCall = tripApiService.postTripPhoto(
tripId,
((GlobalInfo) getApplicationContext()).getApiAccessToken(),
direction,
requestBody);
</code></pre>
<p>But I got this error:</p>
<pre><code>java.lang.IllegalArgumentException: @Body parameters cannot be used with form or multi-part encoding.
</code></pre>
<p>What's wrong with my code? what should I do?</p>

SFSpeechRecognizer - detect end of utterance : <p>I am hacking a little project using iOS 10 built-in speech recognition. I have working results using device's microphone, my speech is recognized very accurately.</p>
<p>My problem is that recognition task callback is called for every available partial transcription, and I want it to <strong>detect person stopped talking</strong> and call the callback with <code>isFinal</code> property set to true. It is not happening - app is listening indefinitely.</p>
<p>Is <code>SFSpeechRecognizer</code> ever capable of detecting end of sentence?</p>
<p>Here's my code - it is based on example found on the Internets, it is mostly a boilerplate needed to recognize from microphone source.
I modified it by adding recognition <code>taskHint</code>. I also set <code>shouldReportPartialResults</code> to false, but it seems it has been ignored.</p>
<pre><code> func startRecording() {
if recognitionTask != nil {
recognitionTask?.cancel()
recognitionTask = nil
}
let audioSession = AVAudioSession.sharedInstance()
do {
try audioSession.setCategory(AVAudioSessionCategoryRecord)
try audioSession.setMode(AVAudioSessionModeMeasurement)
try audioSession.setActive(true, with: .notifyOthersOnDeactivation)
} catch {
print("audioSession properties weren't set because of an error.")
}
recognitionRequest = SFSpeechAudioBufferRecognitionRequest()
recognitionRequest?.shouldReportPartialResults = false
recognitionRequest?.taskHint = .search
guard let inputNode = audioEngine.inputNode else {
fatalError("Audio engine has no input node")
}
guard let recognitionRequest = recognitionRequest else {
fatalError("Unable to create an SFSpeechAudioBufferRecognitionRequest object")
}
recognitionRequest.shouldReportPartialResults = true
recognitionTask = speechRecognizer?.recognitionTask(with: recognitionRequest, resultHandler: { (result, error) in
var isFinal = false
if result != nil {
print("RECOGNIZED \(result?.bestTranscription.formattedString)")
self.transcriptLabel.text = result?.bestTranscription.formattedString
isFinal = (result?.isFinal)!
}
if error != nil || isFinal {
self.state = .Idle
self.audioEngine.stop()
inputNode.removeTap(onBus: 0)
self.recognitionRequest = nil
self.recognitionTask = nil
self.micButton.isEnabled = true
self.say(text: "OK. Let me see.")
}
})
let recordingFormat = inputNode.outputFormat(forBus: 0)
inputNode.installTap(onBus: 0, bufferSize: 1024, format: recordingFormat) { (buffer, when) in
self.recognitionRequest?.append(buffer)
}
audioEngine.prepare()
do {
try audioEngine.start()
} catch {
print("audioEngine couldn't start because of an error.")
}
transcriptLabel.text = "Say something, I'm listening!"

Printing random characters instead of the same ones : <p>sorry for the horrible title, I have no idea how I'd describe my problem.</p>
<p>I'm trying to generate a code that contains 15 characters. 7 of these are already given and will be called the "base". The other 8 have to be random from 0 to 9.</p>
<p>This is my code</p>
<pre><code>numList = "1", "2", "3", "4", "5", "6", "7", "8", "9", "0"
whatSerial = input("Serial to generate?").upper()
def redmi4A(numList):
return "8655920" + numList + numList + numList + numList + numList + numList + numList + numList + " -> Redmi 4A"
if whatSerial == "4A":
for i in numList:
print(redmi4A(i))
</code></pre>
<p>however the output looks like this: </p>
<pre><code>865592011111111 -> Redmi 4A
865592022222222 -> Redmi 4A
865592033333333 -> Redmi 4A
865592044444444 -> Redmi 4A
865592055555555 -> Redmi 4A
865592066666666 -> Redmi 4A
865592077777777 -> Redmi 4A
865592088888888 -> Redmi 4A
865592099999999 -> Redmi 4A
865592000000000 -> Redmi 4A
</code></pre>
<p>as you can see it generates the base + 11111, 2222, 3333 etc.
I want the numbers after the base to output all possible solutions, so the numbers after the base would be in a random order.</p>

Why exactly is void async bad? : <p>So I understand why returning void from async would normally make no sense, but I've ran into a situation where I think it would be perfectly valid. Consider the following contrived example:</p>
<pre><code>protected override void OnLoad(EventArgs e)
{
if (CustomTask == null)
// Do not await anything, let OnLoad return.
PrimeCustomTask();
}
private TaskCompletionSource<int> CustomTask;
// I DO NOT care about the return value from this. So why is void bad?
private async void PrimeCustomTask()
{
CustomTask = new TaskCompletionSource<int>();
int result = 0;
try
{
// Wait for button click to set the value, but do not block the UI.
result = await CustomTask.Task;
}
catch
{
// Handle exceptions
}
CustomTask = null;
// Show the value
MessageBox.Show(result.ToString());
}
private void button1_Click(object sender, EventArgs e)
{
if (CustomTask != null)
CustomTask.SetResult(500);
}
</code></pre>
<p>I realize this is an unusual example, but I tried to make it simple and more generalized. Could someone explain to me why this is horrible code, and also how I could modify it to follow conventions correctly?</p>
<p>Thanks for any help.</p>
