PHP Exercises: Check if a given array of integers contains 5 next to a 5 somewhere
110. Contains 5 Next to 5 Check in Array
Write a PHP program to check if a given array of integers contains 5 next to a 5 somewhere.
Sample Solution:
PHP Code :
<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($nums)
{
// Iterate through the elements of the array up to the second-to-last element
for ($i = 0; $i < sizeof($nums) - 1; $i++) { // Check if the current element is 5 and is equal to the next element if ($nums[$i] == 5 && $nums[$i] == $nums[$i + 1]) return true; } // Return false if there are no consecutive elements equal to 5 return false; } // 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, 9, 10, 17])); var_dump(test([1, 5, 5, 9, 10, 17, 5, 5])); ?>
Sample Output:
bool(false) bool(true) bool(true)

- Write a PHP script to scan an array of integers and return true if any two adjacent elements are both 5.
- Write a PHP function to iterate through an array and check for consecutive occurrences of the number 5.
- Write a PHP program to use a loop to compare neighboring elements and verify the presence of a pair of 5's.
- Write a PHP script to determine if the given array contains a 5 immediately followed by another 5 using index-based comparisons.
