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 Python (3.8.2) (judge verdict: Accepted)

#! python3
#  solve_119_A.py

S = input()
date = S[0:4]+S[5:7]+S[8:10] #yyyymmdd式に変更

tag = 20190430

if int(date) <= 20190430:
    print("Heisei")
else:
    print("TBD")
