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

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


using System;

namespace A
{
	static class Program
	{
		static void Main(string[] args)
		{
			var line = Console.ReadLine();
			var lineSplited = line.Split(new char[] {'/'}, StringSplitOptions.RemoveEmptyEntries);

			var y = int.Parse(lineSplited[0]);
			var m = int.Parse(lineSplited[1]);
			var d = int.Parse(lineSplited[2]);

			if (y < 2019
				|| (y == 2019 && m < 4)
				|| (m == 4 && d <= 30)) {
				Console.WriteLine("Heisei");
				return;
			}

			Console.WriteLine("TBD");
		}
	}
