Score : 100 points

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()
T = [c for c in S]
if int(T[0]) * 1000 + int(T[1]) * 100 + int(T[2]) * 10 + int(T[3]) <= 2018 or  (int(T[0]) * 1000 + int(T[1]) * 100 + int(T[2]) * 10 + int(T[3]) == 2019 and int(T[5]) * 1000 + int(T[6]) * 100 + int(T[8]) * 10 + int(T[9]) <= 430 ):
  print('Heisei')
  exit()
print('TBD')
