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

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

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

int main(void) {
  char s[11];
  
  scanf("%s", s);  
    
  if ((int)(s[5] - '0') == 0 && (int)(s[6] - '0') <= 4 && (int)(s[8] - '0') <= 3) {
    printf("Heisei");
  } else {
    printf("TBD");
  }
  
  return 0;
}
