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.

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

using System;
class Program{
	static void Main(string[] args){
    	string[] input = Console.ReadLine().Split('/');
      	int[] IntIn = new int[3];
      
      	for(int i = 0;i < IntIn.Length ;i ++){
        	IntIn[i] = int.Parse(input[i]);
        }
      if(IntIn[0] >= 2019 && IntIn[1] > 4){
      	Console.WriteLine("TBD");
      }else{
      	Console.WriteLine("Heisei");
      }
      
      
    }
}
