If you really have a desire to do this with Python lists: SCALE_MULTIPLE = 2 # or any positive integer new_array = [] for orig_row in original: new_row = [] for orig_elem in orig_row: new_row.extend([orig_elem] * SCALE_MULTIPLE) new_array.extend(new_row[:] for _ in range(SCALE_MULTIPLE)) 3 solved array resize proportionally in python [closed]
I suppose you’re looking for this: $input = array(“teamA”,”teamB”,”teamC”); $data = []; foreach($input as $value){ $assign = “50”; /* The data just temp */ $data[$value] = $assign; } echo $data[“teamA”]; If $assign is same for all keys: $data = array_fill_keys($input, 50); 1 solved How to make array inside in foreach loop – php?

As a simple example you can declare a boolean variable so inside loop if the value at least found once then assign it true otherwise if the loop returns and the value not found then inform the user that search not found. Also you do not need an inner loop only one loop and input … Read more
For this you can create a new array where you can store the desired values. Then loop (in this case from 0 to 15) and check if the number is in the array-array. If it is not in the array, you can store the value in the values-array. var array = [2, 4, 5, 8, … Read more
If you are looking for a code that generates random numbers between the given range, the below code is for you import java.util.Scanner; import java.util.Random; public class Insert { static Scanner input=new Scanner(System.in); public static void main(String [] args){ Random rand=new Random(); int max,min; System.out.println(“enter the maximum number”); max=input.nextInt(); System.out.println(“enter the minimum number”); min=input.nextInt(); int … Read more
I try to copy the string into the array of string literals What you are trying to do isn’t legal C++. char* MapIds[5000] = … should be const char* MapIds[5000] = … and trying to overwrite anything in that array makes your program have undefined behavior. I try to stay away from std::string and instead … Read more
if unsorted[0] <<== unsorted[1] then numsmall = unsorted[a] ^ (eval):51: syntax error, unexpected kTHEN, expecting kEND That little ^ points to first problem here. <<== is not a legal operator in ruby, hence the syntax error. Perhaps you mean “less than or equal to” which is <=? if unsorted[a] <= unsorted[b] Also, indentation will help … Read more

I am assuming your arr is a POD (plain old data) array. You could make it in C++ a class and overload the operator[] to do runtime index checking. You usually cannot do what you want, and if you could, it would be strongly implementation and operating system dependent. On Linux, access permission to data … Read more
The program has following issues: Array indexing is wrong : Array is of size 5 starting from 0 , you can use only till a[4] , but for scanf() , it tries to read value as &a[5]. No use of for loop when you are using hard coded index a[1],a[2],etc. Instead the below code will … Read more
Based on the example you provided, it seems to me that you want to repeatedly add the same elements (plural) into your array a particular N number of times. Because arrays are fixed in size, you can’t declare int[] a1 = {1,2,3};and then attempt to add more elements to it. That is why I recommend … Read more
Use EXPLODE inside foreach <?php $yourArr = array(‘2,3′,’2,3’); $a = 0; $b =0; foreach ($yourArr as $temp) { $tempnew = explode(“,”,$temp); $a += $tempnew[0]; $b += $tempnew[1]; } echo “a = “.$a.”<br>”; echo “b = “.$b; ?> 1 solved How to Adding values of two dimnetional array in php [closed]
To answer your question “How to return the matrix”: you are already doing it the right way. As you can see from the comments so far, the problem lies in the declaration of A. A is declared and initialized inside the for-loop: int [][]A = new int [size_num][size_num]; Hence its visibility is limited to the … Read more
