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

        try {
            Date d = sdf.parse(s);

            if (d.compareTo(sdf.parse("2019/04/30")) <= 0) {
