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

#include<stdio.h>
#include<string.h>
char s[100];
char a[100];
int main()
{
	gets(s);
   if(strlen(s)==2)
	{
		puts(s);
	}
	if(strlen(s)==3)
	{
		for(int j=2;j>=0;j--)
		{
			printf("%c",s[j]);
		}
		printf("\n");
	}
	return 0;
