The simplest solution is to split the string into a collection of string then sort that collection and concatenate the result into a string again: you can use a custom comparator using the size of the string and feed it to std::stable_sort with the collection of strings to sort: // Your original string std::string your_string … Read more

That’s because allLogs is lazy in nature — it will actually hit the database when first enumerated through in the foreach (see “Deferred query execution” here). If you materialize the collection before hand like the following, you will see that it steps through the foreach quickly: db.StatusLogs .Where(sl => sl.ID.Value.Equals(foo)) .GroupBy(sl=>sl.bar) .ToList(); // <– pull … Read more
This is your solution : public class NewMain { public static void main(String args[]) throws ParseException { Scanner s = new Scanner(System.in); char yes; do { System.out.println(“Hi”); yes = s.next().charAt(0); } while (yes == ‘Y’); // if u enter ‘Y’ the it will continue } } To exit enter any thing other then ‘Y’ 0 … Read more
I hope I’ve understood correctly what you wanted to ask. First of all as it was already mentioned you can’t store integers in String array. Secondly, in Java two-dimensional array is actually the array of arrays. So when you declare int[][] nums = int[4][3] you create an int[] array nums that has four elemets and … Read more
pro.waitFor(); is a blocking method. It will wait until the process has exited before returning. The problem with this is many programs will not exit until there standard out buffers have been read/cleared, meaning, in your case, it probably will never exit. Try something like this instead… import java.io.File; import java.io.IOException; import java.io.InputStream; public class … Read more
You need to create imageview dynamically. ImageView images[]; View shelfRow[] =new View[numberOfRows]; for (int i = 0; i < numberOfRows; i++) { images = new ImageView[numberOfRows]; shelfRow[i].setBackgroundResource(R.drawable.shelf_row2); images[i].setBackgroundColor(android.R.color.black); parentPanel.addView(shelfRow[i]); } Or create 10 imageviews and give id to it like.. int[] buttonIDs = new int[] {R.id.button1ID, R.id.button2ID, R.id.button3ID, … }; View shelfRow[] =new View[numberOfRows]; ImageView[] … Read more
double is not enough for the precision you should use high-precision to solve it 6 solved Online Judgement System – Why am I getting Wrong Answer for this thread? [closed]
If I understand you, you could with this – int count = 0; for (boolean[][] bArrArr : StarTrack) { for (boolean[] bArr : bArrArr) { for (boolean b : bArr) { if (b) { count++; } } } } System.out.println(count); Given your StarTrack I get the output of 6 2 solved Count the number of … Read more

It depends on the return value of the function. If this is void the function does not have a return value and you do the first. callOne(1, 2); If it has something else like int, char or std::string you can use the first but also the second. callTwo = func2(5, 9); In this case you … Read more
Just use the python datetime module: import datetime dayOfWeek = datetime.datetime(y, m, d).weekday() dayOfWeek will then be an integer between 0 and 6 corresponding to Monday – Sunday. Have a look at the docs for more details. solved Can anyone translate this into python? [closed]
