Assuming $arr is your initial array, and $new_arr will be the new one. $new_arr = array(); foreach ($arr as $i=>$ar) foreach ($ar as $j=>$a) $new_arr[$i][$j] = round(($a/array_sum($ar))*100, 1); solved Sum up values in multidimensional php array [closed]
your code seems tidy! Replace your code from for (int i = 0; i < line.Length; i++) and place this int i=0; while (i < line.Length) { if (line[i] != ‘ ‘) { numbers[numCount] = “”; while (line[i] != ‘ ‘) { numbers[numCount] += line[i]; i++; if (i >= line.Length) break; } numCount++; } i++; … Read more
public static long weightedSum(int[] a, int[] b, int n) { if (n == 0) return 0; else return a[n – 1] * b[n – 1] + weightedSum(a, b, n – 1); } Output : int[] arr1 = { 1, 2, 3, 4, 5 }; int[] arr2 = { 6, 7, 8, 9, 10 }; System.out.println(weightedSum(arr1, … Read more
You can transform your object around to get your desired result, first, transform your object to the following using .map() with Object.entries(): [ [ { “service”: “A” }, { “service”: “B” } ], [ { “cost”: 20 }, { “cost”: 50 } ] ] Next, zip these two inner arrays together (the first element of … Read more
To read the data $unsortedData = json_decode(file_get_contents(“data.json”), true); the second paramater true make you get an associative array, instead of getting an array of objects (stdclass) to sort the array: usort($unsortedData, function($a, $b){ return $a[‘serial’] < $b[‘serial’]; }); usort will sort the data according the callback passed as the second parameter, so you can customize … Read more
I think you are looking for this: #include<cstdlib> int v; for(int i=0; i<10; i++) { v = rand() %6; printf(“%s\n”, words[v]); } 1 solved Outputting to console from Char Array
Array.prototype.toObject = function(){ // var length = this.length – 1; return this.reduce(function(obj, val, index, array) { if(index %2 != 0) return obj; // if(index == length) return obj; // leave the ‘e’ property obj[val] = array[index+1]; return obj; }, {}) } var a = [‘a’, ‘b’, ‘c’,’d’, ‘e’, ‘f’]; console.log(a.toObject()); solved How do you convert … Read more
This code doesn’t use the enhanced for loop properly: for (int i : myInts) { if (myInts[i] != 0) { newInts[i] = myInts[i]; } } It tries to read element i from myInts, but i is the content of an element, not its index. So, as soon as some element contains a value > array’s … Read more
Please check with following code $source=array( “0” => array( “status_change” => “start”, “clock_status” => “1” ), “1” => array( “status_change” => “stop”, “clock_status” => “2” ), “2” => array( “status_change” => “stop”, “clock_status” => “2” ), “3” => array( “status_change” => “stop”, “clock_status” => “2” ), “4” => array( “status_change” => “stop”, “clock_status” => “2” … Read more
this is what you try to parse: “+91 72072 21721 +91 79 8105 5662 ” step one, perform a .split(“\\+”); on your String, it will actually split it in the seperate numbers. Next, remove all the spaces of the number you try to parse, so you’ll end up parsing “917207221721” and “917981055662” This will bring … Read more
This data structure is very difficult to deal with. I would consider if this is the best way to store this data. Maybe an array of structs that represent your data? The confusing part is your variable is named array, but it is really declared as a Dictionary literal. So to access the item with … Read more
Let’s consider your example… A = (5, 5, 1, 2, 3, 4, 5) If you consider the first element – 5 – then we know any solution must have one non-5 value at the other end, so we work backwards to find the first non-five, keeping track of the “front” and “back” locations we’re working … Read more
If you can do an increment of one, just repeat that the required number of times. A better way would be: (let’s call the increment n); store the end n elements in another array; move the elements before that towards the end of the array; copy back the elements from the other array to the … Read more
