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-----
5 7 9

-----Sample Output-----
win

5+7+9=21, so print win.
