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

Sample Input 2

2019/11/01

Sample Output 2

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

#!/usr/bin/env python3
b = 0
s = input()
if int(s[:4]) < 2019:
    b = 1
elif int(s[:4]) == 2019:
    if int(s[5:7]) < 4:
        b = 1
    elif int(s[5:7]) == 4:
        if int(s[9:11]) <=30:
            b = 1

if b:
    print('Heisei')
else:
    print('TBD')
