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

Solution in C# (Mono 4.6.2.0) (judge verdict: Runtime Error)

using System;

public class Program
{

    static void Main()
    {
        string[] S = Console.ReadLine().Split('/');

        string y = S[0] + S[1] + S[2] + S[3];
        string m = S[4] + S[5];
        string d = S[6] + S[7];

        int year = int.Parse(y);
        int month = int.Parse(m);
        int day = int.Parse(d);

        if (year <= 2019 && month <= 4 && day <=30)
        {
            Console.WriteLine("Heisei");
        }
        else
        {
            Console.WriteLine("TBD");
        }
    }
}
