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 Fortran (gfortran v4.8.4) (judge verdict: Wrong Answer)

character(10) :: s
integer :: y,m,d

read*,s

read(s(1:4),*),y
read(s(2:3),*),m
read(s(2:3),*),d

if( y<2019 ) goto 200
if( y>2020 ) goto 100
if( m<3 ) goto 200
if( m>5 ) goto 100
if( d<31 ) goto 100


100 continue
print*,'TBD'
stop
200 continue
print*,'Heisei'
stop
end
