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: Wrong Answer)

import java.text.SimpleDateFormat;
import java.util.*;

public class Main {

  static Scanner sc = new Scanner(System.in);

  public static void main(String[] args) throws Exception {

    String S = sc.next();

    SimpleDateFormat sdFormat = new SimpleDateFormat("yyyy/mm/dd");
    Date d = sdFormat.parse(S);

    Date d2 = sdFormat.parse("2019/04/30");

    if (d.compareTo(d2) <= 0) {
      System.out.println("Heisei");
    } else {
      System.out.println("TBD");
    }

  }
