Problem Statement

Given are three integers A_1, A_2, and A_3.

If A_1+A_2+A_3 is greater than or equal to 22, print bust; otherwise, print win.

Constraints

1 \leq A_i \leq 13 \ \ (i=1,2,3)

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A_1 A_2 A_3

Output

If A_1+A_2+A_3 is greater than or equal to 22, print bust; otherwise, print win.

Sample Input 1

5 7 9

Sample Output 1

win

5+7+9=21, so print win.

Sample Input 2

13 7 2

Sample Output 2

bust

13+7+2=22, so print bust.

Solution in Rust (1.15.1) (judge verdict: Accepted)

use std::io::Read;

fn main() {
	let mut s = String::new();
	std::io::stdin().read_to_string(&mut s).unwrap();
	let ints: Vec<_> = s.trim().split(" ").map(|i| i32::from_str_radix(i, 10).unwrap()).collect();
	if ints[0] + ints[1] + ints[2] >= 22 {
		println!("bust");
	} else {
		println!("win");
	}
}
