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

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;
using System.Collections.Generic;
using System.Linq;

class Program{

  static string ans = "Heisei";

  static int Main() {

    string[] nyu = Console.ReadLine().Split('/');
    int y = int.Parse(nyu[0]);
    int m = int.Parse(nyu[1]);
    int d = int.Parse(nyu[1]);

    // ここまで入力

    if (y > 2019) {
      ans = "TBD";
    } else {
      if (m > 4) {
        ans = "TBD";
      }
    }

    Console.WriteLine("{0}", ans);

    return 0;
  }
