// Reverse String using Java 8 Streams (Alternative)

public class Main {
    public static void main(String[] args) {
        // Step 1: Define the original string
        String originalString = "functional";

        // Step 2: Collect characters into a StringBuilder and then reverse
        String reversedString = originalString.chars() // Get an IntStream of char codes
                                    .collect(StringBuilder::new,
