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

Solution in C# (Mono 4.6.2.0) (judge verdict: Runtime Error)

using System;

namespace At_Coder_Beginner_Contest147__A_Blackjack
{
    class Program
    {
        static void Main(string[] args)
        {
            int A1, A2, A3;
            A1 = int.Parse(Console.ReadLine());
            A2 = int.Parse(Console.ReadLine());
            A3 = int.Parse(Console.ReadLine());

            if (A1+A2+A3>=22)
            {
                Console.WriteLine("bust");
            }
            else if (A1+A2+A3<=21)
            {
                Console.WriteLine("win");
            }
            Console.ReadKey();
        }
    }
