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: Accepted)

function Main(input) {
	// 1行目がinput[0], 2行目がinput[1], …に入る
	input = input.split(' ');
	//文字列から10進数に変換するときはparseIntを使います
	var a = parseInt(input[0], 10);
	var b = parseInt(input[1], 10);
	var c = parseInt(input[2], 10);
    var ans = "win";
	if(a + b + c > 21){
      ans = "bust";
    }
	console.log(ans);
}
//*この行以降は編集しないでください（標準入出力から一度に読み込み、Mainを呼び出します）
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
