Solution in Java (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main{
	public static void main(String[] args) throws IOException {
		try (BufferedReader br = new BufferedReader(
				new InputStreamReader(System.in))) {

			String in = br.readLine();
			String chr[] = in.split("/");
			int y = Integer.parseInt(chr[0]);
			int m = Integer.parseInt(chr[1]);

			 System.out.println(y<=2019&&m<5?"Heisei":"TBD");
		}
