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:

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

import java.util.Scanner

object Main {
  def main(args: Array[String]): Unit = {
    val sc: Scanner = new Scanner(System.in)
    val Array(y, m, d) = sc.nextLine.split("/").map(_.toInt)

    if (y >= 2020) {
      println("TBF")
    } else if (y == 2019) {
      if (m >= 5) {
        println("TDB")
      } else {
        println("HEISEI")
      }
    }
    else {
      println("HEISEI")
    }
  }
}
