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:

#include<bits/stdc++.h>
using namespace std;
#define ll long long int
#define all(V) V.begin,V.end
const int N = 100005;

int main()
{
    ios_base::sync_with_stdio(false);
    cin.tie(0);
    cout.tie(0);
    string s;
    cin >> s;
    if(s[5]>'0' || s[6]>'4')
    cout << "TBD";
    else if(s[5]=='0' && s[6]=='4')
    {
        if(s[9]>'0')
        cout << "Heisei";
        else
        {
            cout << "TBD";
        }
        
    }
    else
    cout << "Heisei";
