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:

S

Output

Print Heisei if the date represented by S is not later than April 30, 2019, and print TBD otherwise.

Sample Input 1

2019/04/30

Sample Output 1

Heisei

Sample Input 2

2019/11/01

Sample Output 2

TBD

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

#include <stdio.h>
 
int main(void){
 
  char date[10];
  
  scanf("%s",date);
  
  if(date[5] == '1')
    printf("TBD");
  
  if(date[5] == '0'){
    if(date[6] == '1')
      printf("Heisei");
    else if(date[6] == '2')
      printf("Heisei");
    else if(date[6] == '3')
      printf("Heisei");
    else if(date[6] == '4')
      printf("Heisei");
       
    else
    printf("TBD");
  }
  
 
return 0;
