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 std::io;
use std::str::FromStr;

fn input<T:FromStr>() -> T {
    let mut line: String = String::new();
    io::stdin().read_line(&mut line);
    line.trim().parse().ok().unwrap()
}

fn main() {
    let s: String = input();
    let s: Vec<&str> = s.split("/").collect();
    let year: i32 = s[0].parse().unwrap();
    let month: i32 = s[1].parse().unwrap();
    let day: i32 = s[2].parse().unwrap();
    let mut heisei = true;
    if year > 2019 {
        heisei = false;
    } else if year == 2019 {
        if month > 4 {
            heisei = false;
        } else if month == 4 {
            if day > 30 {
                heisei = false;
            }
        }
    }
    if heisei {
        println!("Heisei");
    } else {
        println!("TBD");
    }
