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.

            string[] inputs = Console.ReadLine().Split(' ');
            int a1 = int.Parse(inputs[0]);
            int a2 = int.Parse(inputs[1]);
            int a3 = int.Parse(inputs[2]);
            string retStr = string.Empty;

            int sumA = a1 + a2 + a3;

            if(sumA >= 22)
            {
                retStr = "bust";
