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 Rust (1.15.1) (judge verdict: Accepted)

fn main() {
    let (_y, m, _d): (usize, usize, usize) = {
        use std::io::Read;
        let mut s = String::new();
        std::io::stdin().read_to_string(&mut s).unwrap();
        s.truncate(10);
        let mut iter = s.split('/');
        let y = iter.next().unwrap().parse().unwrap();
        let m = iter.next().unwrap().parse().unwrap();
        let d = iter.next().unwrap().parse().unwrap();
        (y, m, d)
    };

    println!("{}", if m <= 4 {"Heisei"} else {"TBD"});
}
