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 input = {
        use std::io::*;
        let mut input = String::new();
        let _ = stdin().read_to_string(&mut input);
        input.remove(4);
        input.remove(6);
        input.trim().parse::<i32>().unwrap()
    };
    println!("{}", if input <= 20190430 { "Heisei" } else { "TBD" });
}
