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: Runtime Error)

s = input()
if s[3] == "9":
  if s[5] == 1:
    print("TBD")
  else:
    if int(s[6]) == 1:
      print("TBD")
    else:
      if int(s[7]) > 4:
        print("TBD")
      else:
        print("Heisei")
    
else:
  print("Heisei")
