Palindrome Check Example: PHP vs C++

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 C++

#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

bool isPalindrome(string str) {
    string clean;
    // Keep alphanumeric chars and convert to lowercase
    for(char c : str) {
        if(isalnum(c)) {
            clean += tolower(c);
        }
    }
    
    string reversed = clean;
    reverse(reversed.begin(), reversed.end());
    return clean == reversed;
}

int main() {
    cout << boolalpha;
    cout << isPalindrome("A man, a plan, a canal: Panama") << endl; // true
    cout << isPalindrome("race a car") << endl; // false
    return 0;
}

Bubble Sort Example: PHP vs C++

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 C++

#include <iostream>
#include <vector>
using namespace std;

void bubbleSort(vector<int>& arr) {
    int n = arr.size();
    for(int i = 0; i < n; i++) {
        for(int j = 0; j < n - i - 1; j++) {
            if(arr[j] > arr[j + 1]) {
                swap(arr[j], arr[j + 1]);
            }
        }
    }
}

int main() {
    vector<int> arr = {64, 34, 25, 12, 22, 11, 90};
    bubbleSort(arr);
    
    for(int num : arr) {
        cout << num << " ";
    }
    return 0;
}
