Practice Task 4: Implement a recursive function to reverse a string. For example, given the input "hello", the function should return "olleh"

Recursive String Reversal in Java

This project demonstrates a recursive function that takes a string as input and returns the reversed version of that string.

Example

public class StringReversal {
    public static String reverseString(String input) {
        if (input.isEmpty()) {
            return input;
        }
        return reverseString(input.substring(1)) + input.charAt(0);
    }

    public static void main(String[] args) {
        String input = "hello";
        String reversed = reverseString(input);
        System.out.println("Original string: " + input);
        System.out.println("Reversed string: " + reversed);
    }
}

This will output:

Original string: hello
Reversed string: olleh

Another Output

How it Works

The reverseString() function uses recursion to reverse the input string. Here's how it works:

1. If the input string is empty, the function simply returns the empty string.
2. Otherwise, the function recursively calls itself with the substring of the input string starting from the second character (i.e., input.substring(1)).
3. The function then concatenates the result of the recursive call with the first character of the input string (input.charAt(0)).

This process continues until the base case (an empty string) is reached, at which point the function starts to unwind the recursive calls and build the reversed string.
