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 Scala (2.11.7) (judge verdict: Runtime Error)

object Main{
import scala.io.StdIn.readLine
val a_list:List[Int] = readLine().split(" ").map(_.toInt).toList
if (a_list.foldLeft(0)((x,y) => x + y) <= 21){println("win")}
  else {println("bust")}
}
