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

S

Output

Sample Input 2

Solution in Ruby (2.3.3) (judge verdict: Accepted)

cnt = 0
n = gets.chomp.split("/").map(&:to_i)
if n[0] <= 2019
  if n[1] <= 4
    if n[2] <= 30
      puts "Heisei"
      cnt += 1
    end
  end
end
if cnt == 0
  puts "TBD"
end
