Problem K:
Accidentally, the grader did not accept submissions that used "+0" (only those that used
"-0") in the absolute term of the polynomial. This was fixed and the problem was rejudged,
with several changes from WA to OK. Additionally, one team now has a more helpful WA
message telling them that their submission was not a 7-bit ASCII text file. Sorry about
the issue.

We are aware that there is no completely fair solution to the issues some teams had with problem M
due to the fact that the site was not responsive during some minutes. We apologize
for the trouble this may have caused you, and we hope that the issues won't come back.
The best solution we came up with is the following one:
- If your restaurant is running, we will reset your reputation to 10 as a one-time change.
- If you already have humans, we will remove them as a one-time change.
- If your restaurant is closed but you reopen it before 17:30 UTC, the previous two items will apply to it as well.

-
In particular, we are aware that this impacts solvability of problem M.
This is something we will address if and when the issue is resolved.
(There is no need to send us messages detailing how your team was affected.)

We are aware of issues with the responsiveness of the webserver, and
we are trying to deal with them. Please be patient.

Problem L:
Please note that (as stated in the statement) in the file you submit
you have to print at least one empty line between consecutive games.
If the empty lines are missing, our grader will parse the entire submission
as a single game.

Problem E:
Corrections were made in the example annotation:
In sample 1, correct set of good values is {1, 5 6, 10, 12}.
In sample 4, the correct number is 142816 142817.
A corrected version of the statement will be uploaded in a minute.
- 2018-10-06 15:32:00 UTC
-
Problem G:
There was a typo in the statement.
The correct example checksum is 649, not 646.
A corrected version of the statement will be uploaded in a minute.
