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";
main(require("fs").readFileSync("/dev/stdin", "UTF-8"));

function main(input) {
  let result = 0;
  input
    .split("\n")[0]
    .split(" ")
    .map(n => (result += Number(n)));
  if (result < 22) {
    console.log("win");
  } else {
    console.log("bust");
  }
}
