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 (1.42.0) (judge verdict: Wrong Answer)

fn main() {
    proconio::input!(
        s: String
    );
    let s: String = s;
    let date: Vec<usize> = s.split("/").map(|c| c.parse::<usize>().unwrap()).collect();
    let ans = if let [y, m, d] = date[..] {
        if y < 2019 {
            "Heisei"
        } else if y > 2019 {
            "TBD"
        } else if m > 5 {
            "TBD"
        } else {
            "Heisei"
        }
    } else {
        ""
    };
    println!("{}", ans);
}
