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

S is a string that represents a valid date in the year 2019 in the yyyy/mm/dd format.

Input

Input is given from Standard Input in the following format:

Sample Output 1

Heisei

Sample Input 2

Solution in Scala (2.11.7) (judge verdict: Wrong Answer)


object Main extends App {
  val ss = io.StdIn.readLine.split('/')

  val year = ss(0).toInt
  val month = ss(1).toInt
  val day = ss(2).toInt

  val out =
    if (year >= 2019 && month >= 4 && day >= 30)
      "Heisei"
    else
      "TBD"

  println(out)
}
