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.

Solution in Python (3.4.3) (judge verdict: Accepted)

# encoding: utf-8
# N = int(input())
# N, M = map(int, input().split())
# A = list(map(int, input().split()))
# AB = [list(map(int, input().split())) for i in range(N)]

S = input()

if len(S) == 2: print(S)
else: print(S[::-1])
