PHP Exercises: Find out the maximum element between the first or last element in a given array of integers, replace all elements with maximum element

PHP Basic Algorithm: Exercise-92 with Solution

Write a PHP program to find out the maximum element between the first or last element in a given array of integers ( length 4), replace all elements with maximum element.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($nums)
 { 
    // Find the maximum value in the array using the 'max' function
    $max = max($nums);

    // Return a new array containing four copies of the maximum value
    return [$max, $max, $max, $max];
 }   

// Create an array $a with some numeric values
$a = [10, 20, -30, -40];

// Print the original array as a string using 'implode' and 'echo'
echo "Original array: " . implode(',', $a) . "\n";

// Call the 'test' function with the array $a and store the result in $result
$result = test($a);

// Print the new array with four copies of the maximum values using 'implode' and 'echo'
echo "New array with maximum values: " . implode(',', $result);
?>

Sample Output:

Original array: 10,20,-30,-40
New array with maximum values: 20,20,20,20
