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 C# (Mono 4.6.2.0) (judge verdict: Wrong Answer)

using System;
public class Program{
    public static void Main(){
        string[] input =Console.ReadLine().Split(' ');
        var a=int.Parse(input[0]);
        var b=int.Parse(input[1]);
        var c=int.Parse(input[2]);
        var s=a+b+c;
        Console.WriteLine(s);
        if(s>=22){
            Console.WriteLine("bust");
        }else if(s<22){
            Console.WriteLine("win");
        }
        
    }
}
