using System;

namespace ABC119_a
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] array = Console.ReadLine().Split('/');
            int a = int.Parse(array[0]);
            int b = int.Parse(array[1]);
            int c = int.Parse(array[2]);
            if(a < 2019)
            {
                Console.WriteLine("Heisei");
                
            }else if((a == 2019) && (b <= 04))
            {
                Console.WriteLine("Heisei");
            }
            else
            {
                Console.WriteLine("TBD");
            }
            
            
        }
