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: Accepted)

using System;
    using System.Collections.Generic;
    using System.Text;
    class Program
    {
        static void Main(string[] args)
        {
            string input = Console.ReadLine();
            int a1 = int.Parse(input.Split(' ')[0]);
            int a2 = int.Parse(input.Split(' ')[1]);
            int a3 = int.Parse(input.Split(' ')[2]);

            if (a1 + a2 + a3 >= 22)
            {
                Console.WriteLine("bust");
            }
            else
            {
                Console.WriteLine("win");

            }

        }
    }
