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:

Solution in C++14 (GCC 5.4.1) (judge verdict: Accepted)

#include <iostream>
using namespace std;
string s;
int main(){
  cin >> s;
  int m = (s[5] - '0') * 10 + (s[6] - '0');
  int d = (s[8] - '0') * 10 + (s[9] - '0');
  if (m <= 4 && d <= 30) cout << "Heisei" << endl;
  else cout << "TBD" << endl;
  return 0;
}
