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 <iostream>
#include <cstdio>
#include <vector>
#include <algorithm>
#include <string>

using namespace std;

int main()
{

    string s;
    string answer = "TBD";

    cin >> s; //~2019/04/30

    int year, month, day;
    year = stoi(s.substr(0, 4));
    month = stoi(s.substr(5, 2));
    // day = stoi(s.substr(8, 2));

    if (year < 2019)
    {
        answer = "Heisei";
    }
    else if (year == 2019)
    {
        if (month < 5)
            answer = "Heisei";
    }

    cout << answer << endl;

    return 0;
