        String reversed = reverse(input);
        System.out.println("Reversed String is " + reversed);
    }

    private static String reverse(String input) {

        if (input.length() == 1) {
            return input;
        } else {
            return reverse(input.substring(1, input.length())) + input.charAt(0);
