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

#include <iostream>

using namespace std;

vector<string> split(const string &str, char sep)

    string buffer;
    while( getline(ss, buffer, sep) ) {
        v.push_back(buffer);
    }
    return v;
}

int main() {
    string s;
    cin >> s;
    vector<string> v = split(s, '/');
    int year = atoi(v[0].c_str());
    int month = atoi(v[1].c_str());
    int day = atoi(v[2].c_str());
    if(year < 2019) {
        cout << "Heisei" << endl;
        return 0;
    }
    if(year == 2019 && month <= 4 && day <= 30) {
        cout << "Heisei" << endl;
        return 0;
    }
    cout << "TBD" << endl;
