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 12.16.1) (judge verdict: Accepted)

const main = stdin => {
  const input = stdin.trim().split('\n')
  const [A, B, C] = stdin.trim().split(' ').map(x => parseInt(x))
  A + B + C >= 22 ? console.log('bust') : console.log('win')
}

// 標準入力
main(require("fs").readFileSync("/dev/stdin", "utf8"))
