Score : 100 points

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)

function main (input){
	const inputs = input.split('');
	const length = inputs.length;
	let num = 0;
	for (let i = 0; i < length; i++){
		if(inputs[i] !== inputs[length - 1 -i]) {
			num++;
		}
	}
	console.log(num / 2);
}

main(require('fs').readFileSync('/dev/stdin', 'utf8'));
