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 (3.8.2) (judge verdict: Runtime Error)

s = str(input())
year = ''
month = ''
day = ''

for i in range(4):
    y = s[i]
    year += y
for i in range(5, 7):
    m = s[i]
    month += m
for i in range(9, 11):
    d = s[i]
    day += d

year = int(year)
month = int(month)
day = int(day)

if year < 2019:
    answer = 'Heisei'

elif year == 2019 and month <= 4:
    answer = 'Heisei'

else:
    answer = 'TBD'
    
print(answer)
