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:

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

import java.util.*;


public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);

		String s=sc.next();
		String y=s.split("/")[0];
		String m=s.split("/")[1];
		String d=s.split("/")[2];
		int year=Integer.parseInt(y);
		int month=Integer.parseInt(m)+10;
		int day=Integer.parseInt(d);
		if(year>=2020 || (year==2019 && month>=15)){
			System.out.println("TBD");
		}else if((year==2019 && month <=14 )|| year<=2018){
			System.out.println("Heisei");
		}
