Problem Statement

You are given a string S of length 2 or 3 consisting of lowercase English letters. If the length of the string is 2, print it as is; if the length is 3, print the string after reversing it.

Constraints

The length of S is 2 or 3.

S consists of lowercase English letters.

Input

Input is given from Standard Input in the following format:

S

Output

If the length of S is 2, print S as is; if the length is 3, print S after reversing it.

Sample Input 1

abc

Sample Output 1

cba

As the length of S is 3, we print it after reversing it.

Sample Input 2

ac

Sample Output 2

ac

As the length of S is 2, we print it as is.

#include <stdio.h>
int main(){
  
    int A,B,K,i,a,b;
  
    scanf("%d", &A);
    scanf("%d", &B);
    scanf("%d", &K);
  
    i = 0;
    while(i < K){
      if(A % 2 == 1){
        A -= 1;
      }
      a = A / 2;
      A = a;
      B += a;
      ++i;
      if(i < K){
        break;
      }
      else if(B % 2 == 1){
        B -= 1;
      }
      b = B / 2;
      A = A + b;
      B = b;
      ++i;
    }
  
    printf("%d %d \n", A, B);
  
    return 0;
