PHP Exercises: Check if the sum of all 5' in the array exactly 15 in a given array of integers
PHP Basic Algorithm: Exercise-112 with Solution
Write a PHP program to check if the sum of all 5' in the array exactly 15 in a given array of integers.
Sample Solution:
PHP Code :
<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($nums)
{
// Initialize a variable $sum with a value of 0
$sum = 0;
// Iterate through the elements of the array using a for loop
for ($i = 0; $i < sizeof($nums); $i++)
{
// Check if the current element is equal to 5, increment $sum by 5 if true
if ($nums[$i] == 5)
$sum += 5;
}
// Return true if the sum is equal to 15, otherwise return false
return $sum == 15;
}
// Use 'var_dump' to print the result of calling 'test' with different arrays
var_dump(test([1, 5, 6, 9, 10, 17]));
var_dump(test([1, 5, 5, 5, 10, 17]));
var_dump(test([1, 1, 5, 5, 5, 5]));
?>
Sample Output:
bool(false) bool(true) bool(false)
