[ad_1] If I understand correctly you can do it like the following, but it is an XY problem, why are you not structuring your arrays properly first? $normalised = []; foreach ($array as $key => $value) { list($k, $a) = explode(‘-‘, $key, 2); $normalised[$k][$a] = $value; } 4 [ad_2] solved split an array into multiple … Read more
[ad_1] You are using the * to separate “main items” but it can also be inside the main item. Your requirements look odd, but lets assume for the sake of argument that you are getting your input data like this and you want to split it like you suggested. That means that every * that … Read more
[ad_1] Yes, by design. The single-equals means set the left operand to the right operand. The 4th element of Array1 is set to the value of the fourth element of Array2. This changes the contents of the array, though not the structure. If you’re trying to do a comparison, you’ll want to use == for … Read more
[ad_1] You can Decode json data in view.blade.php like this : <tbody> @foreach($vehicles as $vehicle) <tr> <td> @foreach(json_decode($vehicles->plate_number) as $plate) {{ $plate[‘variable_name’] }} @endforeach </td> <td>{{ $vehicles->delivery_capacity }}</td> </tr> @endforeach </tbody> [ad_2] solved How to use json decoded data in blade laravel
[ad_1] You used to have str.split(“,”); and split() is a void method. It doesn’t alter str. you could fix it by replacing str.split(“,”) with: str = str.split(“,”), or you could put it all on one line like: while ((str = br1.readLine()) != null) userstr.add(str.split(“,”)[0]); 2 [ad_2] solved How can I separate a single String into … Read more
[ad_1] Since you’re working with arrays and not ArrayList objects, things get a little tedious. The following code runs through the first array, checks if the current String is not the one you don’t want, and increases the counter by one if it has found one you do want. It then creates a new array … Read more
[ad_1] Python does not have arrays like in C, unless you install the Numpy library (which I recommend if you are trying to work mathematical and numerical processing problems). Numpy is not necessary to solve this problem. If you want a 2D array you can use nested lists: each row is a list, like this: … Read more
[ad_1] If you want to include 0*constant: let arr = Array(0..<size).map { $0 * constant } If you don’t want to (i.e., start at 1*constant): let arr = Array(1..<size).map { $0 * constant } If you don’t want to multiply by a constant (or the constant is 1): let arr = Array(0..<size) [ad_2] solved pick … Read more
[ad_1] In your for loop, i correctly iterates from 0 to the maximum length. However you have code such as: tweetArray[i+1] … tweetArray[i+7] that will fail once i reaches (or gets close to) its maximum. That is, you are referencing past the end of the array. In general, if you need to check something about … Read more
[ad_1] If I understood your requirement correctly, you can just use bracket notation like obj[‘a’].name var obj = { a: { “name”: “Emma” }, b: { “name”: “Harry” }, c: { “name”: “Jonny” } }; var ary = [‘a’, ‘b’, ‘c’] for (var i = 0; i < ary.length; i++) { console.log(obj[ary[i]].name) } Here you … Read more

[ad_1] Not quite sure what output you want, but probably you want to output the strings in the array. You can’t detect the end of an array directly. You either need to put a sentinel value at the end of the array, for example NULL: #include <stdio.h> int main(void) { char *t[10] = { “Program”, … Read more

[ad_1] You almost got it, change it to like this var grades = [100, 90, 100, 50, 80, 60]; function countFailing(gradesArr){ var counter = 0; for (var i = 0; i < gradesArr.length; i++){ if (gradesArr[i] < 70 ) counter++; } return counter; } alert(countFailing(grades)); DEMO HERE [ad_2] solved How to make a function take … Read more
[ad_1] Here is how I accomplished this. There is probably a better way, but we need to create a new array in memory with the alpha-characters as the actual keys (basically we are removing the parent arrays we don’t need). Then we use ksort to actually sort the array. <?php $test = array( array(“a” => … Read more
