Palindrome Check Example: PHP vs Java

Palindrome Check in PHP

<?php
function isPalindrome($str) {
    $clean = preg_replace("/[^a-zA-Z0-9]/", "", strtolower($str));
    return $clean === strrev($clean);
}

// Example usage
echo isPalindrome("A man, a plan, a canal: Panama") ? "true" : "false"; // true
echo "\n";
echo isPalindrome("race a car") ? "true" : "false"; // false
?>

Palindrome Check in Java

public class PalindromeChecker {
    public static boolean isPalindrome(String str) {
        String cleanStr = str.toLowerCase().replaceAll("[^a-z0-9]", "");
        return cleanStr.equals(new StringBuilder(cleanStr).reverse().toString());
    }

    public static void main(String[] args) {
        System.out.println(isPalindrome("A man, a plan, a canal: Panama")); // true
        System.out.println(isPalindrome("race a car")); // false
    }
}

Bubble Sort Example: PHP vs Java

Bubble Sort in PHP

<?php
function bubbleSort($arr) {
    $n = count($arr);
    for ($i = 0; $i < $n; $i++) {
        for ($j = 0; $j < $n - $i - 1; $j++) {
            if ($arr[$j] > $arr[$j + 1]) {
                $temp = $arr[$j];
                $arr[$j] = $arr[$j + 1];
                $arr[$j + 1] = $temp;
            }
        }
    }
    return $arr;
}

$arr = array(64, 34, 25, 12, 22, 11, 90);
print_r(bubbleSort($arr));
?>

Bubble Sort in Java

public class BubbleSort {
    public static void bubbleSort(int[] arr) {
        int n = arr.length;
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < n - i - 1; j++) {
                if (arr[j] > arr[j + 1]) {
                    int temp = arr[j];
                    arr[j] = arr[j + 1];
                    arr[j + 1] = temp;
                }
            }
        }
    }

    public static void main(String[] args) {
        int[] arr = {64, 34, 25, 12, 22, 11, 90};
        bubbleSort(arr);
        System.out.println(Arrays.toString(arr));
    }
}
