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

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

# -*- coding: utf-8 -*-
#
# a = list(map(int, input().split('/')))
#
# # print(a)
#
# if a[0] <= 2018:
#     print('Heisei')
# else:
#     if a[0] == 2019 and a[1] <= 4:
#         print('Heisei')
#     else:
#         print('TBD')
#
#

S = input()

S = int(S[5:7])

if S <= 4:
    print('Heisei')
else:
    print('TBD')
