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.

import java.util.*;

public class Main {
    public static void main(String args[]) {
       ///値を取得
       Scanner sc = new Scanner(System.in);
       int a1 = sc.nextInt();
       int a2 = sc.nextInt();
       int a3 = sc.nextInt();
       int sum = a1 + a2 + a3;
       
       //出力
       if(sum >= 22) {
           System.out.print("bust");
       } else if(sum <= 21) {
           System.out.print("win");
       }
    }
