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

Heisei

Sample Input 2

2019/11/01

Sample Output 2

TBD

Solution in Fortran (gfortran v4.8.4) (judge verdict: Accepted)

Program ABC119A

integer y,m,d
character(1) a,b

read'(i4,a1,i2,a1,i2)', y,a,m,b,d

if(m<=4) then
 write(*,*) 'Heisei'
else
 write(*,*) 'TBD'
end if

stop
end
