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# (.NET Core 3.1.201) (judge verdict: Accepted)

using System;

namespace abc147_a
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] A123 = Console.ReadLine().Split(" ");
            int sum = int.Parse(A123[0]) + int.Parse(A123[1]) + int.Parse(A123[2]);

            string str;
            if(sum >= 22)
            {
                str = "bust";
            }
            else
            {
                str = "win";
            }
            Console.WriteLine(str);
        }
    }
}
