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 PHP (5.6.30) (judge verdict: Wrong Answer)

A,B,C = map(str,input().split("/"))
if int(A) <= 2018:
  print("Heisei")
elif int(A) == 2019 and int(B) <=4 and int(C)<=30:
  print("Heisei")
else:
  print("TBD")
