PHP Exercises: Get the absolute difference between n and 51

PHP Basic Algorithm: Exercise-2 with Solution

Write a PHP program to get the absolute difference between n and 51. If n is greater than 51 return triple the absolute difference.

Sample Solution:

PHP Code :

<?php
// Define a function named "test" that takes a parameter $n
function test($n) 
{
    // Declare a variable $x and assign it the value 51
    $x = 51;

    // Check if $n is greater than $x
    if ($n > $x)
    {
        // If true, return the result of multiplying the difference between $n and $x by 3
        return ($n - $x) * 3;
    }

    // If false, return the difference between $x and $n
    return $x - $n;
}

// Call the test function with argument 53 and echo the result
echo test(53) . "\n";

// Call the test function with argument 30 and echo the result
echo test(30) . "\n";

// Call the test function with argument 51 and echo the result
echo test(51) . "\n";
?>
