Palindrome Check Example: C++ vs Swift

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;
}

Palindrome Check in Swift

func isPalindrome(_ str: String) -> Bool {
    let clean = str.lowercased().filter { $0.isLetter || $0.isNumber }
    return clean == String(clean.reversed())
}

# Example usage
print(isPalindrome("A man, a plan, a canal: Panama")) // true
print(isPalindrome("race a car")) // false

Bubble Sort Example: C++ vs Swift

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;
}

Bubble Sort in Swift

func bubbleSort(_ arr: inout [Int]) {
    let n = arr.count
    for i in 0..<n {
        for j in 0..<(n - i - 1) {
            if arr[j] > arr[j + 1] {
                arr.swapAt(j, j + 1)
            }
        }
    }
}

# Example usage
var arr = [64, 34, 25, 12, 22, 11, 90]
bubbleSort(&arr)
print(arr)
