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

import java.util.Scanner;
class Main
{
	public static void main(String args[])
	{
		Scanner sc=new Scanner(System.in);
        String s=sc.next();
        String year0=s.substring(0,4);
        int year1=Integer.parseInt(year0);
        String day0=s.substring(8);
        int day1=Integer.parseInt(day0);

        if(year1<=2019){
            if(s.charAt(5)=='0'&&s.charAt(6)<='4'){
                if(day1<=30){
                    System.out.println("Heisei");
                }
                else{
                    System.out.println("TBD");
