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 (1.42.0) (judge verdict: Accepted)

use proconio::{input, fastout};
use proconio::marker::{Chars};
#[fastout]
fn main() {
    input!{
        _s: Chars,
    }

    let s: String = _s.iter().collect();
    let y = &s[0..4];
    let year: usize = y.parse().unwrap();
    let m = &s[5..7];
    let month: usize = m.parse().unwrap();
    // let d = &s[8..10];
    // let day = d.parse().unwrap();

    if year < 2019 {
        println!("Heisei");
        return;
    } else {
        if month <= 4 {
            println!("Heisei");
            return;
        } else {
            println!("TBD");
        }
    }
