Problem Statement

You are given a string S as input. This represents a valid date in the year 2019 in the yyyy/mm/dd format. (For example, April 30, 2019 is represented as 2019/04/30.)

Write a program that prints Heisei if the date represented by S is not later than April 30, 2019, and prints TBD otherwise.

Constraints

S is a string that represents a valid date in the year 2019 in the yyyy/mm/dd format.

Input

Input is given from Standard Input in the following format:

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
#include <stdlib.h>
#include <string.h>


int main(void){
   
   char M[100];
   
   scanf("%s",M);
   
   int M1 = M[5] - '0';
   int M2 = M[6] - '0';
   
   int D1 = M[8] - '0';
   int D2 = M[9] - '0';

   
   if(M1 == 0 && M2 <= 4){
      printf("Heisei\n");
   }
   else {
      printf("TBD\n");
   }
 
   return 0;
   
}
