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(){
  char s[12];
  scanf("%s",s);
  int year=1000*(s[0]-'0')+100*(s[1]-'0')+10*(s[2]-'0')+s[3]-'0';
  int month=10*(s[5]-'0')+s[6]-'0';
  int day=10*(s[8]-'0')+s[9]-'0';
  if(year>2019)
    printf("TBD\n");
  else if(year==2019){
    if(month>4)
      printf("TBD\n");
    else
      printf("Heisei\n");
  }
  return 0;
}
