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;

class MinMax {  
  static void Main() {  
    
     string[] str = Console.ReadLine().Split();
     
     int A1 = int.Parse(str[0]);
     int A2 = int.Parse(str[1]);
     int A3 = int.Parse(str[2]);
     int sum = A1 + A2 + A3;

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