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.

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

"use strict";

const main = arg => {
  const a = arg.split(" ").map(x=>parseInt(x));
  if(a[0]+a[1]+a[2]>21){
  	console.log("bust");
  }
  else{
    console.log("win");
  }
  return;
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
