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()

y = int(s[:4])
m = int(s[5:7])
d = int(s[8:])

yup = False
if y < 2019:
  yup = True
elif y == 2019:
  if m < 4:
    yup = True
  elif m == 4:
    if d <= 30:
      yup = True
    
      
      
if not yup:print('TBD')
else : print('Heisei')
