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: Wrong Answer)

#include<stdio.h>
int main(void){
  int i=0;
  char S[11],T[]="2019/04/30";
  scanf("%s",S);
  while(i<=9 && S[i]>='0' && S[i]<='9'){
    if(i==4 || i==7){
      continue;
    }
    if(S[i]>=T[i]){
      printf("TBD\n");
      return 0;
    }
  }
  printf("Heisei\n");
  return 0;
}
