With recent changes to statement sample became wrong; I think sample input should now look like:

BID 0.01
BID 10000.00
BID 5000.00
BID 5000.00
SALE 7000.00 3
DEL 5000.00
SALE 3000.00 3
SALE 0.01 3
QUIT

, am I right?

We have replaced "exactly 2 digits" by "at most 2 digits" in the problem statement. Thank you.
