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 a[11];
  scanf("%s", a);

  int i = 5;
  int month = 0;
  int monthTmp = 0;

  while(i <= 6){
    monthTmp = (a[i] - '0');
    int j = i;
    while(j < 6){
      monthTmp = monthTmp * 10;
      j++;
    }
    month = month + monthTmp;
    i++;
  }

  if(month >= 5){
    printf("TBD");
  } else {
    printf("Heisei");
  }

  return 0;
}
