PHP Exercises: Check a given array of integers and return true if the value 5 appears 5 times and there are no 5 next to each other

PHP Basic Algorithm: Exercise-120 with Solution

Write a PHP program to check a given array of integers and return true if the value 5 appears 5 times and there are no 5 next to each other.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($numbers)
 { 
    // Initialize variables $flag and $five with values of false and 0, respectively
    $flag = false;
    $five = 0;

    // Iterate through the elements of the array using a for loop
    for ($i = 0; $i < sizeof($numbers); $i++)
    {
        // Check if the current element is 5 and $flag is false
        if ($numbers[$i] == 5 && !$flag)
        {
            // Increment $five and set $flag to true if the condition is met
            $five++;
            $flag = true;
        }
        else
        {
            // Set $flag to false if the current element is not 5
            $flag = false;
        }
    }

    // Return true if there are five consecutive occurrences of 5, otherwise false
    return $five == 5;
 }   

// Use 'var_dump' to print the result of calling 'test' with different arrays
var_dump(test([3, 5, 1, 5, 3, 5, 7, 5, 1, 5]));
var_dump(test([3, 5, 5, 5, 5, 5, 5]));
var_dump(test([3, 5, 2, 5, 4, 5, 7, 5, 8, 5]));
var_dump(test([2, 4, 5, 5, 5, 5]));
?>

Sample Output:

bool(true)
bool(false)
bool(true)
bool(false)
