56,855,310 | im a big c++ noob and I need help starting out a block of code for my program | <p>so i am making a code that takes data from a txt file and gets its variance.
The formula that my teacher required us to use needs the program to square the decimals in the txt file and then gets its sum. unfortunately i do not have a sample of code because I do not know where to start. I was only able to store the data in the text file into a vector.</p>
<pre><code>ifstream dataInput("D:\\Users\\Rodolfo Obre\\Documents\\Ateneo De Manila\\Intersession 2019\\Engg 21\\Programs\\Text Files\\Data Set.txt");
double readNumber;
vector<double> dataSet;
if (!dataInput.is_open()) {
cerr << "The file can not be opened\n";
exit(1);//exits the program
}
while (dataInput >> readNumber){
dataSet.push_back(readNumber);
}
cout << "n is equal to " << dataSet.size() << endl;
double sum=0;
for (int i=0; i < dataSet.size(); i++){
sum += dataSet[i];
}
cout << "The sum of the data is " << sum << endl;
</code></pre>
<p>This block of code takes the data from the txt file, counts how many there are and then takes its sum.</p>
<p>I have no idea how I to do the part where i need to take each decimal in the text file, raise it to the power 2 and then get the sum of all of the values.</p>

56,855,361 | Question about declaration and initialization | <p>I have a question about initialization. When we initialize an array with { }, we must do it right after declaration to show compiler which type to use. Why does compiler allow diamond operator do it with 2 statements?</p>

//Integer[] array; array = {2,4,5}; - error
List<Integer> list = new ArrayList<>();
//List<Integer> list; list = new ArrayList<>(); - no error

56,874,600 | How to generate a unique Long value in Java? | <p>everyone.</p>
<p>I have a simple question. Is the value returned by <code>UUID.randomUUID().getMostSignificantBits()</code> ALWAYS unique?</p>
<p>I need to generate a Long value which needs to ALWAYS be unique. Is there any other way to generate a Long that accomplishes this?</p>
<p>Thanks.</p>

I don't understand how these two can go together, as in how does set.begin() return smallest element when a redblack tree doesn't guarantee the smallest element will be the head. Also set.begin() function makes it seem like this container uses an array instead of a linked list to build the redblack tree, which again I don't understand how an array can be used instead of a tree.Can someone explain me the implementation of c++ set?

<p>-The first one is to skim through and learn about all the types of data structures and how they are implemented.</p>
<p>-The second one is to try instead of just reading and knowing about a data structure, I will go and try to implement it. However, the drawbacks are that its slow and time consuming, so I might not be able to learn all of the data structures in time</p>

56,899,276 | Refreshing data periodically using SignalR rather than broadcasting to clients | <p>I display some of the data i.e. Sum, Average and Total on a page and want to update them after the data changed using SignalR.

<pre><code>private void BroadcastDataChange(Data data)

Clients.All.dataChanged();

<p>However, I am wondering if there is a smarter approach that let me update the data i.e. periodically refreshing without broadcast in each of the create-update-delete methods (I do not use SqlDependency, etc, juts using SignalR). On the other hand, I am not sure this kind of approach is contradictory to the SignalR logic. This is the first time I use SİgnalR and I am too confused :( Any help would be appreciated.</p>

56,905,857 | Algorithm to detect more than one sequence of 4 same letters horizontally, vertically or diagonally | I have been assigned a task to write an algorithm to detect if a given array of strings contains more than one sequence of 4 repeated letters horizontally, vertically or diagonally. They also asked me the most efficient way to do it.
An input example would be something like this:
`String[] input = {"ATGCGA","CAGTGC","TTATGT","AGAAGG","CCCCTA","TCACTG"};`
but you guys can see it more clearly like a table here:
A T G C G A
C A G T G C
T T A T G T
A G A A G G
C C C C T A
T C A C T G
This array contains 3 sequences with a repeated letter:
AAAA is found diagonally
CCCC is found horizontally
GGGG is found vertically
So, since there are more than 1 sequence found in this input example, the output should be true.
I have an idea to solve this problem but my major issue is handling the diagonals, especially using an efficient way to do it since they expect to use this function in a high concurrency environment.
I would be grateful for any help provided. It's ok if someone can't write the code, but at least some ideas to get the right approach to solve this problem.

ASCII Converter enables you to easily convert ASCII characters to their hex, decimal, and binary representations. In addition, base64 encode/decode binary data. As you type in one of the text boxes above, the other boxes are converted on the fly.
The ASCII converter doesn't automatically add spaces between the converted values. You can use the add spaces button to separate the ASCII characters so that the converted values will also be separated from one another. | <c#><csv> | 2019-07-05 22:11:12 | LQ_EDIT |

56,922,180 | error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually | <p>This error came up after upgrading to React Native 0.60.</p>
<p>I've tried to manually unlink each manually linked dependency using <code>react-native unlink <dependency></code> as suggested in the error message, but the problem still persists.</p>
<p>The error message is as follows:</p>
<pre><code>error React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:
- react-native-admob (to unlink run: "react-native unlink react-native-admob")
- react-native-facebook-account-kit (to unlink run: "react-native unlink react-native-facebook-account-kit")
- react-native-fbsdk (to unlink run: "react-native unlink react-native-fbsdk")

- react-native-vector-icons (to unlink run: "react-native unlink react-native-vector-icons")
- react-native-webview (to unlink run: "react-native unlink react-native-webview")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above. Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically. If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.

56,923,006 | Front Degradation Issue | I'm beginning to learn the basics of HTML and CSS and am currently working through the FreeCodeCamp program. Currently, I cannot create an account to access the forums there so I'm going to attempt to solve it here. Within the problem, it's asking the user to add a second font and comment out the Google font import at the top. Everything is correct and accepted as so yet it's saying the H2 element must use the "Lobster" font. The problem is that the current font is already set the "Lobster".
I've tried adding a separate font-family beneath the Lobster font, but this removes the functionality of the degradation feature. This did not work. I also attempted to rearrange the formatting of the code but doing so breaks it even more. Here are the directions.
Your h2 element should use the font Lobster.
Your h2 element should degrade to the font monospace when Lobster is not available.
Comment out your call to Google for the Lobster font by putting <!-- in front of it.
Be sure to close your comment by adding -->.
<!--<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">-->
<style>
.red-text {
color: red;
}
h2 {
font-family: Lobster, monospace;
}
p {
font-size: 16px;
font-family: monospace;
}

I expect everything to be correct as is, and for this to be an error on the program's end. Unlikely.. but I'm confident I followed the directions accurately. | <html><css><fonts> | 2019-07-07 14:27:54 | LQ_EDIT |
