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(int argc, char const *argv[]) {
  char S[10];
  for (size_t i = 0; i < 10; i++) {
    scanf("%c", &S[i]);
  }
  int tuki=10*(S[5]-'0')+S[6]-'0';
  int niti=10*(S[8]-'0')+S[9]-'0';
  if (tuki>=5 || (tuki==4 && niti==31)) {
    printf("TBD");
    return 0;
  }
  printf("Heisei");
  return 0;
}
