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

Solution in C++14 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <iostream>
#include <string>
using namespace std;

int main() {
    int N;
    double x, sum = 0;
    string u;
    const double BTC_RATE = 380000.0;

    cin >> N;
    for (int i=0; i<N; i++) {
        cin >> x >> u;
        if (u == "BTC") {
            cout << "BTC" << endl;
            sum += x * BTC_RATE;
        } else {
            sum += x;
        }
    }

    cout << sum << endl;

    return 0;
