Something like this might work for you: var i; var k; for(i = 0; i < existingArray.length; i++){ var count = 2; for(k = 0; k < existingArray.length; k ++){ if(i != k && existingArray[i].content.host.name === existingArray[k].content.host.name){ existingArray[k].content.host.name += ‘_’ + count; count++; } } } 3 solved How to modify an array of objects … Read more

We can use map, filter reduce for this, it’s slightly tricky but the same principle applies: const data = { periods: [ { decisions: [ { bank: { name: “Team1” }, bSPositionDecisions: [ { totalInputRate: 1.0, positionValue: 12, balanceSheetPosition: { name: “asset_bc_lombard_a_onsight”, category: “LOMBARD_LOANS”, type: “ASSET” } }, { totalInputRate: 2.0, positionValue: 10, balanceSheetPosition: { … Read more
To find the average in the given array and find the number which is closest to the average, public static void main(String[] args) { int array[] = new int[] { 1, 2, 3, 4, 5, 6, 7, 8 }; int sum=0; double avg; for (int i = 0; i < array.length; i++) { sum += … Read more
In the public static String Calculate() function, you need to return return sgrade; and currently, you are not returning any object, but the method calls for the return of a string. Also, remove String sgrade = d.readLine(); from line 199 (in the addData function). This is causing problems, because you are defining a new variable … Read more
If you need to allocate a TEST object dynamically then you can do this: int main(int argc, char * argv[]) { //Just to fill an array with some integers int rows = 3; int cols = 3; TEST* t = new TEST; t->row = rows; t->col = cols; t->a = new int*[rows]; for(int i = … Read more
You need to be more precise when you write code. Your array of integers has a different number than the example output you want. I thought perhaps you wanted a set for a response, but there were two fails in there, so I ruled that out, too. Another source of imprecision are the ranges you … Read more
Does this return what you want? [[1,2] , [3,7] , [2,9] , [10,19]].sorted(by: {$0[0]<$1[0]}) 3 solved Is there a way to sort an array by a subarray’s index in Swift?

This program uses a logic in which we rotate an array by reversing array in parts. First we will reverse array upto index location and then reverse remaining array ( index+1 to last element of array). After completing above two steps we call again reverse function but this time on whole of the array that … Read more
Change JSONArray list = new JSONArray(Jo_result.getString(“result”)); To JSONObject list = new JSONObject(Jo_result.getString(“result”)); Your string is contained between {} which makes it an object. Keep in mind this {} = Json Object [] = Json Array UPDATE When you do this JSONObject resultsObject = list.getJSONObject(i); it’s expecting another object within the main object, for example : … Read more
Shuffle it with shuffle(): shuffle($xbb); Searching Google for php shuffle array will give you tons of results as well, by the way. solved php random array – random again when doing while [duplicate]
There’s several problems with your code. First, the swap function doesn’t work. You’re swapping the values of the pointers that are local variables inside the function, you’re not swapping the array elements they point to. You need to indirect through pointers to get the values. int temp1 = *a; *a = *b; *b = temp1; … Read more
There are several ways to do this, you can do this with the help of traditional for, Math.max(), indexOf() and Array#reduce. First of all, you need to find the maximum value of your input array, then you should pop it and according to the iteration count, iterate to find the next maximum value. Then after … Read more
Here you go: <?php $array = array( array(1,2), array(3,4), array(5,6), array(7,8) ); function processArray(&$array) { for ($i = 0; $i < count($array); $i++) { if ($array[$i][0] > 4) { $array[$i][0] = $array[$i][0] – 3; } if ($array[$i][1] < 5) { $array[$i][1] = $array[$i][1] + 3; } } } processArray($array); print_r($array); Outputs: Array ( [0] => … Read more
