find a pair of elements from an array whose sum equals a given number in java

I have the following array

    [0] => Array
            [gender] => F
            [thisweektotal] => 3

    [1] => Array
            [gender] => M
            [thisweektotal] => 2

    [2] => Array
            [gender] => Adult
            [thisweektotal] => 1

    [3] => Array
            [gender] => Young Adult
            [thisweektotal] => 4


I want the sum of thisweektotal of the gender M and F only that is 5 I have tried the below code but i am not getting sum of all the gender F and I want only the sum of the genders M and F

foreach($analytics_data['this_week'] as $value) 

    if($value['gender']=='M' || $value['gender']=='F')
      $total_this_week_arr = array_column($value['thisweektotal'], 'thisweektotal');
      $this_week_total = array_sum($total_this_week_arr);


 echo "this_week_total=".$this_week_total;

Since you are looping, you dont need the array_column and array_sum. You can just:

$this_week_total = 0;

foreach($analytics_data['this_week'] as $value)  {
    if( $value['gender'] == 'M' || $value['gender'] == 'F' )
      $total_this_week_arr = $value['thisweektotal'];
      $this_week_total += $total_this_week_arr ;

echo "this_week_total = " .$this_week_total;

Array sum in C++ STL, How do you find the sum of an array element in C++? Write a JavaScript function to calculate the sum of values in an array. Test Data: Omits the key-value pairs corresponding to the given keys from an object.

You're looping through the array just you need a variable which holds the sum value

$sum = 0;//Your variable which stores the value of sum

foreach($analytics_data['this_week'] as $k=>$arr){
    if($arr['gender']=='F' || $arr['gender']=='M')
    $sum+=$arr['thisweektotal']; //Adding sum to $sum

echo $sum;

How To Find All Pairs of Elements In An Array Whose Sum Is Equal , How do you find all pairs of an integer array whose sum is equal to a given number? S = sum(A) returns the sum of the elements of A along the first array dimension whose size does not equal 1. If A is a vector, then sum(A) returns the sum of the elements. If A is a matrix, then sum(A) returns a row vector containing the sum of each column. If A is a multidimensional array, then sum(A)

Here's a solution using array_column with the third paramter which works because you don't have conflicting values in the "gender" key transforming the array to a much simplier structure for summing.

$gender = array_column( $array, 'thisweektotal', 'gender' );
$total = $gender['M'] + $gender['F'];

If there is a chance of a missing key we can try using array_intersect_key as a sort of a "whitelist filter" to your array...

$gender = array_column( $array, 'thisweektotal', 'gender' );
$filtered = array_intersect_key( $gender, array_flip( array( 'M', 'F' ) ) );
$total = array_sum( $filtered );

Given an array A[] and a number x, check for pair in A[] with sum as x , whose sum is equal to the given value. bool hasArrayTwoCandidates( given sum" ;. else Duration: 10:35 Posted: Oct 10, 2011 After my array gives me random values, I want to be able to get the sum of those values. The method I'm using now isn't working, it gives me an incorrect calculation.

$aInput = [
        "gender" => "F",
        "thisweektotal" => 3,
    ], [
        "gender" => "M",
        "thisweektotal" => 2,
    ], [
        "gender" => "Adult",
        "thisweektotal" => 1,
    ], [
        "gender" => "Young Adult",
        "thisweektotal" => 4,

$iSum = array_reduce($aInput, function($sum, $el) {
    if (in_array($el['gender'], ['F', 'M'])) {
        $sum += $el['thisweektotal'];
    return $sum;
