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++14 (GCC 5.4.1) (judge verdict: Accepted)

#define _GLIBCXX_DEBUG
#include <bits/stdc++.h>
using namespace std;


int main(){
  string date;
  cin >> date;
  string y, m, d;
  for (int i = 0; i < 4; i++) y = date.substr(0, 4);
  for (int i = 0; i < 2; i++) m = date.substr(5, 2);
  for (int i = 0; i < 2; i++) d = date.substr(8, 2);

  int y_ = atoi(y.c_str());
  int m_ = atoi(m.c_str());
  int d_ = atoi(d.c_str());

  if (y_ <= 2019 && m_ <= 4 && d_ <= 30) cout << "Heisei" << endl;
  else cout << "TBD" << endl;
}
