PHP: Exercise-44 with Solution

Write a PHP program to print out the sum of pairs of numbers of a given sorted array of positive integers which is equal to a given number.

Sample Solution: -

PHP Code:

<?php
function find_Pairs($nums, $pair_sum) {
  $nums_pairs = "";
  for ($i = 0; $i <= count($nums); $i++) {
     for ($j = $i + 1; $j < count($nums); $j++) {
        if ($nums[$i] + $nums[$j] == (int)$pair_sum) {
           $nums_pairs .= $nums[$i] . "," . $nums[$j] . ";";
        }
     }
  }
  return $nums_pairs;
}
$nums = array(0,1,2,3,4,5,6);
echo find_Pairs($nums, 7)."\n";
echo find_Pairs($nums, 5)."\n";
?>

Sample Output:

1,6;2,5;3,4;                                                
0,5;1,4;2,3;
