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: Runtime Error)

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

int main(void){
  char tmp[12];
  char *year;
  char *month;
  int y, m, d;
//  scanf("%s", m);
//  printf("aaaaa");
//  y = 2019;
//  m = 03;
//  d = 16;

  year = strtok(tmp, "/");
  month = strtok(NULL, "/");

  y = atoi(year);
  m = atoi(month);
  d = atoi(tmp);
  
  if(y > 2019){
    printf("TBD");
  }else if( y < 2019){
    printf("Heisei");
  }else if( m > 4){
    printf("TBD");
  }else if(m < 4){
    printf("Heisei");
  }else if(d > 30){
    printf("TBD");
  }else{
    printf("Heisei");
  }
    
 return 0;
