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;

namespace ABC147_A
{
    class Program
    {
        static void Main(string[] args) {
            string[] input = Console.ReadLine().Split();
            string ans = "bust";

            int ans2 = 0;
            for (int i = 0; i < input.Length; i++) {
                ans2 += int.Parse(input[i]);
            }

            if (ans2 >= 22) {
                Console.WriteLine("bust");
                return;
            }
            ans = "win";

            Console.WriteLine(ans);
        }
    }
}
