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)

S = gets.chomp.to_s
s = (S[0].to_i)*10000000+(S[1].to_i)*1000000+(S[2].to_i)*100000+(S[3].to_i)*10000+(S[5].to_i)*1000+(S[6].to_i)*100+(S[8].to_i)*10+(S[9].to_i)
if s <= 20190430
    puts "Heisei"
else 
    puts "TBD"
end
