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 Ruby (2.3.3) (judge verdict: Accepted)

array = []

input = gets.chomp

array = input.split("/")

year = array[0].to_i
month = array[1].to_i
day = array[2].to_i

if year < 2019
  puts "Heisei"
elsif year == 2019 && month < 4
    puts "Heisei"
  elsif year == 2019 && month == 4 && day <=30
      puts "Heisei"
  else
    puts "TBD"
  end
