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

Solution in Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		
		String n = sc.nextLine();
		
		int y = Integer.parseInt(n.substring(0, 4));
		int m = Integer.parseInt(n.substring(5, 7));
		int d = Integer.parseInt(n.substring(8, 10));
		
		if (y <= 2019 && m <= 4 && d <= 30) {
			System.out.println("Heisei");
		}else {
			System.out.println("TBD");
		}
		sc.close();
	}
