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

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

'use strict'
function main(inp) {
  inp = inp.trim().split(' ').map(n => Number(n));
  console.log(inp[0]+inp[1]+inp[2] > 21 ? 'bust' : 'win')
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
