problem_description: 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.
