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:

S

Output

Print Heisei if the date represented by S is not later than April 30, 2019, and print TBD otherwise.

Sample Input 1

2019/04/30

Sample Output 1

Heisei

Sample Input 2

2019/11/01

Sample Output 2

TBD

Solution in Scala (2.11.7) (judge verdict: Accepted)

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 = (year,month,day) match {
    case (2019,m,_) if m <= 4 => "Heisei"
    case (y,_,_) if y >= 2019 => "TBD"
    case _ => "Heisei"
  }

  println(out)
}
