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 C (Clang 3.8.0) (judge verdict: Runtime Error)

#include<stdio.h>

int main(void){
int taka[101];
int aoki[101];
int k,i;
scanf("%d%d%d",&taka[0],&aoki[0],&k);
for(i=0;i<k;i++){
 if(i%2==0){
  if(taka[i]%2==1){
   taka[i]=taka[i]-1;
  }
   taka[i+1]=taka[i]/2;
   aoki[i+1]=aoki[i]+taka[i+1];
}else{
  if(aoki[i]%2==1){
    aoki[i]=aoki[i]-1;
}
    aoki[i+1]=aoki[i]/2;
    taka[i+1]=taka[i]+aoki[i+1];
}
}
printf("%d %d",taka[k],aoki[k]);
return 0;
}
