113. Compare Count of 3's and 5's in Array

Write a PHP program to check if the number of 3's is greater than the number of 5's.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($nums)
 { 
    // Initialize variables $no_3 and $no_5 with values of 0
    $no_3 = 0;
    $no_5 = 0;

    // Iterate through the elements of the array using a for loop
    for ($i = 0; $i < sizeof($nums); $i++)
    {
        // Check if the current element is equal to 3, increment $no_3 if true
        if ($nums[$i] == 3) $no_3++;
        
        // Check if the current element is equal to 5, increment $no_5 if true
        if ($nums[$i] == 5) $no_5++;
    }

    // Return true if the count of 3's is greater than the count of 5's, otherwise return false
    return $no_3 > $no_5;
 }   

// Use 'var_dump' to print the result of calling 'test' with different arrays
var_dump(test([1, 5, 6, 9, 3, 3]));
var_dump(test([1, 5, 5, 5, 10, 17]));
var_dump(test([1, 3, 3, 5, 5, 5]));
?>

Sample Output:

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

Write a PHP script to count the frequency of the numbers 3 and 5 in an array and return true if the count of 3's exceeds that of 5's.
Write a PHP function to tally occurrences of 3 and 5 in an array and compare their counts.
Write a PHP program to implement a counter for specific digits in an array and output a boolean based on the count comparison.
Write a PHP script to use a loop or array_count_values() to determine whether the number 3 appears more frequently than the number 5.

Go to:

PREV : Sum of 5's Equals 15 Check.
NEXT : Contains 3 or 5 in Array Check.
