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 Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.io.*;

public class Main {


    private static String solver(String input) {
        String[] intputArray = input.split("/");
        int year = Integer.parseInt(intputArray[0]);
        int month = Integer.parseInt(intputArray[1]);
        int day = Integer.parseInt(intputArray[2]);

        int dateNum = year * 10000 + month * 100 + day;
        if(dateNum <= 20190430){
            return "Heisei";
        }else{
            return "TBD";
        }
    }


    public static void main(String[] args) {

        InputStreamReader is = new InputStreamReader(System.in);
        BufferedReader br = new BufferedReader(is);
        String input = "";
        try {
            input = br.readLine();
        } catch (Exception e) {
            e.printStackTrace();
        }
        System.out.println(solver(input));

    }
