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

Print Heisei if the date represented by S is not later than April 30, 2019, and print TBD otherwise.

Sample Input 1

2019/04/30

Sample Output 1

Heisei

Sample Input 2

2019/11/01

Sample Output 2

TBD

Solution in Python (3.4.3) (judge verdict: Accepted)

s = input()

if int(s[:4]) > 2019:
    print("TBD")
    exit()
if int(s[:4]) < 2019:
    print("Heisei")

if int(s[5]) * 10 + int(s[6]) > 4:
    print("TBD")
    exit()
if int(s[5]) * 10 + int(s[6]) < 4:
    print("Heisei")
    exit()

if int(s[8]) * 10 + int(s[9]) > 30:
    print("TBD")
else:
    print("Heisei")
