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

#include <iostream>

#include <cmath>
#include <vector>
#include <iomanip>
#include <map>
using namespace std;

void solve(){
  string s; cin >> s;
  string sy, sm, sd;

  for(int i = 0; i < 2; i++) sm[i] = s[4 + i];
  for(int i = 0; i < 2; i++) sd[i] = s[6 + i];
  if(s <= "2019/04/30") cout << "Heisei\n";
  else cout << "TBD\n";
  return;
}

  solve();
  return 0;
