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: Runtime Error)

function main(input) {
    cards.map(card => Number(card))
    const count = cards.reduce((sum,card) => {return sum + Number(card)}, 0)
    if (count>=22) {
        console.log("bust");
    } else {
        console.log("win");
    }
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
