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

Input is given from Standard Input in the following format:

S

Output

2019/04/30

Sample Output 1

Heisei

Sample Input 2

2019/11/01

Solution in Python (3.8.2) (judge verdict: Wrong Answer)

import datetime as d
def main():
    s = d.datetime.strptime(input(), "%Y/%m/%d")
    s = d.date(s.year, s.month, s.day)
    if s <= d.date(2019,4,30):
        print("Heisei")
    else:
        print("TDB")

if __name__ == "__main__":
    main()
