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

Sample Input 2

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

str = gets.chop

/^([^\/]*)\/([^\/]*)\/([^\/]*)$/ =~ str

year = $1.to_i
month = $2.to_i
data = $3.to_i

if (year <= 2019) && (month <= 4) && (data <= 30) then
	print 'Heisei'
else
	print 'TBD'
end
