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: Wrong Answer)

#include <iostream>
#include <string>

using namespace std;

int find(string s, char c) {
	int i;
	for (i = 0; i < s.length(); i++) {
		if (s[i] == c) {
			break;
		}
	}
	return i;
}

int main()
{
	int temp;
	string s,y,m,d;
	int h = 0;

	cin >> s;

	temp = find(s, '/');
	y = s.substr(0, temp);
	// 5 yyyy
	s = s.substr(++temp);
	temp = find(s, '/');
	m = s.substr(0, temp);
	d = s.substr(++temp);

	h = stoi(y) * 10000 + stoi(m) * 100 + stoi(d);

	if (h <= 20190430) {
		cout << "Heisei" << endl;
	}
	else {
		cout << "TBD" << endl;
	}
	cout << y << m << d;
}
