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.*;

class Main{
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String S = br.readLine();
        String [] ymd = S.split("/");
        int[] ymd_num = new int[ymd.length];
        int cont = 0;
        for (String t:ymd){
            ymd_num[cont] = Integer.parseInt(t);
            cont = cont + 1;
        }
        if (ymd_num[0] <= 2018){
            System.out.println("Heisei");
        } else if (ymd_num[0] == 2019 && ymd_num[1] <= 4){
            System.out.println("Heisei");
        } else {
            System.out.println("TBD");
        }
    }
