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;
use std::cmp::Ordering;

fn main(){

    let mut input = String::new();
    io::stdin().read_line(&mut input).expect("Failed to read line");

    let v : Vec<&str> = input.split('/').collect();

    let y : i32 = v[0].parse().unwrap();
    let m : i32 = v[1].parse().unwrap();

    match y.cmp(&2019){
        Ordering::Less => println!("Heisei"),
        Ordering::Equal => match m.cmp(&04){
            Ordering::Less => println!("Heisei"),
            Ordering::Equal => println!("Heisei"),
            Ordering::Greater => println!("TBD"),
        },
        Ordering::Greater => println!("TBD"),
    }
