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)

'use strict';
const main = input => {
  input = input[0].split(' ').map(val => parseInt(val));
  const a = input[0], b = input[1], c = input[2];
  console.log((a+b+c)>=22?'bust':'win');
}
main(require("fs").readFileSync("/dev/stdin", "utf8").split('\n'));
