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)

use std::io::stdin;

fn main () {
    let mut s = String::new();
    stdin().read_line(&mut s).unwrap();
    let s: Vec<isize> = s.trim().split('/').flat_map(str::parse).collect();
    let y = s[0];
    let m = s[1];
    let d = s[2];
    if y > 2019 || (y == 2019 && m >= 5) {
        println!("TBD");
    } else {
        println!("Heisei");
    }
}
