using System;

namespace test
{
    class Program
    {
        static void Main(string[] args)
        {
            string b = Console.ReadLine();
            int a; string an;
            a = b[5] * 10 + b[6];
            if (a > 4) { an = "TBD"; }
            else { an = "Heisei"; }
            Console.Write(an);
        }
