Problem:
Score : 100 points

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 Haskell (GHC 7.10.3) (judge verdict: Accepted)

import Data.List.Split
main = do
    a <-  getLine
    -- let year = take 4
    -- let day =  take 2 $  drop
    let temp = map (\x -> read x) $ splitOn "/" a :: [Int]
    --let temp = map (\x -> read x) $ split '/' a :: [Int]
    let isHeisei = ((temp !! 0) >= 2019) && ((temp !! 1) <= 4) && ((temp !! 2) <= 30)
    putStrLn $ if isHeisei then "Heisei" else "TBD"
