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.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Scanner;

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

      SimpleDateFormat sdFormat1 = new SimpleDateFormat("yyyy/MM/dd");
      Date date = sdFormat1.parse(input);

      SimpleDateFormat sdFormat2 = new SimpleDateFormat("yyyy/MM/dd");
      Date heiseiDate = sdFormat2.parse("2019/04/30");

      String answer = heiseiDate.compareTo(date) < 0 ? "TBD" : "Heisei";
      System.out.println(answer);
    }
  }
