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;

class Program
{
    static void Main(string[] args)
    {
        string str1 = Console.ReadLine();
        string[] arrayA = str1.Split(' ');
        long sum = 0;

        foreach( var strA in arrayA )
        {
            long Ai = Int32.Parse(strA);
            sum += Ai;

            if ( sum >= 22 )
            {
                Console.WriteLine("bust");
                return;
            }
        }

        Console.WriteLine("win");
    }
}
