import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        String str = in.nextLine();
        StringBuffer strb = new StringBuffer(str);
        strb.reverse();
        System.out.println(strb.toString());
    }
}

和之前的那2个题目一模一样...
