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 9.2.1) (judge verdict: Accepted)

#include <bits/stdc++.h>
const int MOD = 1e9+7;
#define REP(i,n) for (int i = 0; i < (n); ++i)
#define ll long long
#define ar array
using namespace std;
using P = pair<int,int>;

int main () {
	ios::sync_with_stdio(0);
	cin.tie(0);

	string S;
	cin >> S;

	if (S=="2019/04/30" || S<="2019/04/30") {
		cout << "Heisei" << endl;
	} else {
		cout << "TBD" << endl;
	}
	return 0;
