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;

fn main() {

    println!("{}", if testg() {"TBD"} else {"Heisei"});
}

fn testg() -> bool {
    let mut input = String::new();
    io::stdin().read_line(&mut input).unwrap();
    let splitter : Vec<&str> = input.trim().split('/').collect();
    let i1 : i32 = splitter[0].parse().ok().unwrap();
    if i1 < 2019 {
        return false
    } else if i1 > 2019 {
        return true
    }

    let i1 : i32 = splitter[1].parse().ok().unwrap();
    if i1 > 4 {
        return true
    } 
    false
}
