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.

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

raw_data = gets
raw_data = raw_data.split("/").map{|n|n.to_i}
year = raw_data[0]
month = raw_data[1]
day = raw_data[2]
answer = "Heisei"
answer = "TBD" if year > 2019
answer = "TBD" if (year == 2019 && month > 4)
answer = "TBD" if (year == 2019 && month == 4 && day > 30)
puts answer
