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)

#![allow(non_snake_case)]

fn main() {
    let mut inbuf = String::new();
    std::io::stdin().read_line(&mut inbuf).unwrap();
    let S = inbuf.trim_right().to_owned();

    let date: Vec<&str> = S.split('/').collect();
    let year: i32 = date[0].parse().unwrap();
    let month: i32 = date[1].parse().unwrap();
    let day: i32 = date[2].parse().unwrap();

    let mut ans = "Heisei";
    if year > 2019 || year == 2019 && month >= 5 {
        ans = "TBD"
    }

    println!("{}", ans);
}
