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 Go (1.6) (judge verdict: Accepted)

package main

import (
	"fmt"
	"os"
)

func run() int {
	var a1, a2, a3 int
	fmt.Scanf("%d %d %d\n", &a1, &a2, &a3)

	if a1+a2+a3 >= 22 {
		fmt.Println("bust")
	} else {
		fmt.Println("win")
	}

	return 0
}

func main() {
	os.Exit(run())
}
