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;
public class test
{
  public static void Main(){
    var input = Console.ReadLine().Split(' ');
    var result = int.Parse(input[0]) + int.Parse(input[1]) + int.Parse(input[2]);
    
    if(result >=22)
    {
      Console.WriteLine("bust");
    }
    else if(result <=21)
    {
      Console.WriteLine("win");
    }
  }
}
