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 <bits/stdc++.h>
using namespace std;

#define IOS ios::sync_with_stdio(0); cin.tie(0); cout.tie(0);

#define int long long int
#define pb push_back
#define mp make_pair
#define ff first
#define ss second

int32_t main()
{
    IOS;

    string str;

    cin>>str;

    if(str.size()==2)
        cout<<str;
    else
    {
        reverse(str.begin(),str.end());
        cout<<str;
    }

    return 0;
