#include <stdio.h>
int main()
{
	char moji[100];
  	int i;
	scanf("%s",moji);
	for(i=0; moji[i]!='\0'; ++i);
   	if(i==2){
      printf("%c",moji[0]);
      printf("%c",moji[1]);
    }
    if(i==3){
      printf("%c",moji[2]);
      printf("%c",moji[1]);
      printf("%c",moji[0]);
    }
	return 0;
