57. Nearest to 13 Without Overrun

Write a PHP program to check two given integers and return the value whichever value is nearest to 13 without going over. Return 0 if both numbers go over.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes two parameters and returns a value based on conditions
function test($x, $y)
{
    // Check if both $x and $y are greater than 13; if true, return 0
    if ($x > 13 && $y > 13) return 0;
    
    // Check if $x is less than or equal to 13 and $y is greater than 13; if true, return $x
    if ($x <= 13 && $y > 13) return $x;
    
    // Check if $y is less than or equal to 13 and $x is greater than 13; if true, return $y
    if ($y <= 13 && $x > 13) return $y;
    
    // If none of the above conditions are met, return the greater of $x and $y
    return $x > $y ? $x : $y;
}

// Test the 'test' function with different input values and display the results
echo (test(4, 5))."\n";
echo (test(7, 12))."\n";
echo (test(10, 13))."\n";
echo (test(17, 33))."\n";
?>

Explanation:

• Function Purpose:
• The test function takes two parameters, $x and $y, and returns a value based on several conditions involving the numbers' relationship to 13.
• Conditions:
• If both $x and $y are greater than 13, it returns 0.
• If $x is less than or equal to 13 and $y is greater than 13, it returns $x.
• If $y is less than or equal to 13 and $x is greater than 13, it returns $y.
• If none of the above conditions are met, it returns the greater of $x and $y.

Output:

5
12
13
0

For more Practice: Solve these Related Problems:

• Write a PHP script to compare two integers and return the one closest to 13 without exceeding 13, returning 0 if both exceed.
• Write a PHP function that evaluates two numbers for proximity to 13 and outputs the nearer value if within limit.
• Write a PHP program to determine the number closest to 13 from two inputs and ignore both if they are above 13.
• Write a PHP script to implement conditional logic that selects the nearest candidate to 13, with a fallback to 0 when both are over.

Previous: Write a PHP program to compute the sum of the three given integers. However, if any of the values is in the range 10..20 inclusive then that value counts as 0, except 13 and 17.
Next: Write a PHP program to check three given integers (small, medium and large) and return true if the difference between small and medium and the difference between medium and large is same.
