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 get_input() -> String {
    let mut word = String::new();
    std::io::stdin().read_line(&mut word).unwrap();
    word.trim().to_owned()
}

fn main() {
	let s = get_input();
    let year:i64 = s[0..4].parse().unwrap();
    let month:i64 = s[5..7].parse().unwrap();
    let day:i64 = s[8..10].parse().unwrap();

    let l = (2019 * 365) + (4 * 30) + 30;
    let m = (year * 365) + (month * 30) + day;
    
    if m <= l {
        println!("Heisei");
    } else {
        println!("TBD");
    }
 }
