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

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

using System;

namespace abc119A
{
    class MainClass
    {
        public static void Main(string[] args)
        {
            string A = Console.ReadLine();
            int B = Int32.Parse(A.Substring(0, 4));
            int C = Int32.Parse(A.Substring(5, 2));
            int D = Int32.Parse(A.Substring(8, 2));
            if (B > 2019)
                Console.WriteLine("TBD");
            else if (C > 4)
                Console.WriteLine("TBD");
            else if (D > 30)
                Console.WriteLine("TBD");
            else
                Console.WriteLine("Heisei");
        }
    }
