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 Kotlin (1.0.0) (judge verdict: Runtime Error)

import java.util.* 
fun main(args: Array<String>){
  val scan = Scanner(System.`in`)
  val A = scan.nextLine().trim().toInt()
  val B = scan.nextLine().trim().toInt()
  val C = scan.nextLine().trim().toInt()
  
  if(A < 0 || B < 0 || C < 0){
    println("bust")
  }else{
  	if((A+B+C) >= 22)
    	println("bust")
    else
    	println("win")
  }
}
