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 Sample
{
  class Sample
  {
    static void Main(string[] args)
    {
      string[] str=Console.ReadLine().Split(' ');
      int a1=int.Parse(str[0]);
      int a2=int.Parse(str[1]);
      int a3=int.Parse(str[2]);
      if(a1+a2+a3>=22){
        Console.WriteLine("bust");
      }else{
      
    
        Console.WriteLine("win");
      }
    }
  }
}
