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)

#include "bits/stdc++.h"
using namespace std;
typedef long long ll;
const ll MOD = 1000000007LL;
const ll INF = 1LL << 60;
const double PI = 3.141592653589793238;
const double EPS = 1e-10;

int main() {
	int y, m, d;
	scanf("%d/%d/%d", &y, &m, &d);
	bool heisei = 0;
	if (y < 2019) heisei = 1;
	else if (y == 2019) {
		if (m < 4) heisei = 1;
		else if (m == 4 && d <= 30) heisei = 1;
	}
	if (heisei) cout << "Heisei" << endl;
	else cout << "TBD" << endl;
