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 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

cba

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

Sample Input 2

#include <bits/stdc++.h>

using namespace std;

int main(){
  string s, t;
  
  cin >> s;
  
  if ( s.length() == 2 ){
    cout << s << endl;
  }else {
    cout << s.at( 2 ) << s.at( 1 ) << s.at( 0 ) << endl;
  }
  //cout << ans << endl;

  
  return 0;
