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{

    static long gcd(long a,long b){
        if(b==0)return a;
        return gcd(b,a%b);
    }

    static long lcm(long a,long b){
        return a/gcd(a,b)*b;
    }
    public static void main(String[] srgs){
        Scanner sc=new Scanner(System.in);

        int a=sc.nextInt();
        int b=sc.nextInt();
        int c=sc.nextInt();
        if(a+b+c>=22)System.out.println("bust");
        else System.out.println("win");
    }
