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

Solution in Ruby (2.7.1) (judge verdict: Accepted)

s=gets.chomp.delete('/').split("").map &:to_i
y=[s[0],s[1],s[2],s[3]].join.to_i
m=[s[4],s[5]].join.to_i
d=[s[6],s[7]].join.to_i
if y<=2019 && (m<4 || (m==4 && d<=30))
  puts :Heisei
else
  puts :TBD
end
