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

using System.Numerics;
class Program
{     
    public void Slove()
    {
        string[] inputs = Console.ReadLine().Split('/');
        int year = int.Parse(inputs[0]);
        int month = int.Parse(inputs[1]);
        bool heisei = 
            (year <= 2018 ||
            (year == 2019 && month < 5));
        Console.WriteLine(heisei ? "Heisei" : "TBD");
    }
    
    static void Main(string[] args)
    {
