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

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

#include <bits/stdc++.h>
#define int long long
using namespace std;

signed main() {
    string s;
    cin >> s;

    string t[3];
    int idx = 0;
    for (char c : s) {
        if (c == '/') idx++;
        else t[idx] += c;
    }

    cout << (t[1] < "05" ? "Heisei" : "TBD") << endl;

    return 0;
}
