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

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

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