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 <stdio.h>
#include <vector>

using std::vector;
using std::cout;
using std::cin;

int gcd(int a, int b){
    if (b == 0) {
        return a;
    }
    return gcd(b, a % b);
}

int main() {
    int64_t a,b,c;
    char temp;
    cin >> a >> temp >> b >> temp >> c;

    int64_t sm = a * 1000000 + b * 10000 + c * 10;
    if (sm < 2019040300) {
        cout << "TBD";
        return 0;
    }

    cout << "Heisei";
    return 0;
}
