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 JavaScript (node.js v5.12) (judge verdict: Runtime Error)

var arr = "";
var n = 3;
var num = 0;
for (var i = 0 ;i < n; i++){
	arr = prompt(i+1);
}
var arrn = arr.split("");
for (var j = 0 ; j<arrn.length ; j++){
	num = parseInt(arrn[j]);
  	num += num;
}
if(num>=22){
	print("burst");
}
else{
  print("win");
}
