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<stdio.h>
#define MAX_LIMIT 20
#include<string.h>
int main()
{
  char str[MAX_LIMIT],temp;
   fgets(str,MAX_LIMIT,stdin);
    int length=0,i,j=0;
  while (str[length] != '\0')
{
 length++;
}
    if(length<3)
{
printf("%s",str);
}
      if(length>=3){
   printf("\nEnter the string :");
   gets(str);
 
   i = 0;
   j = strlen(str) - 1;
 
   while (i < j) {
      temp = str[i];
      str[i] = str[j];
      str[j] = temp;
      i++;
      j--;
   }
     printf("%s", str);
     }
return 0;
