On the official results page for Advanced it appears that our team (I_Cry_Often) did not answer problems 3 and 6 (if that is what blank means), although we did answer them, afaik correctly. We also have a screenshot from the contest that shows our answers shortly before it ended. What should we do in this situation?

Yup, that doesn't fall in any case, so it would give 39. I asked LucaLucaM (the guy below) if they are sure, and they brute-forced it, so 39 is probably correct.

The last was some x-s and one 1, I fixed it in the original, my bad.

From what I understood from the person on my team that solved it, they are:

• all combinations of 1s and 2s -> 25

• some x-s and one x+1, where x is a divisor of 24 without 1 -> 7

• some x-s and one 1, where x is a divisor of 24 without 1, 2 -> 6

This gives 25+7+6=38

For the ones we are sure about I can confirm the answers (all except 2, 9, 13, 15).

We did not solve 9, but I think I found an example coloring for k=1 (RBRBGBGBGRGRGRB), and since k=0 also works the answer can't be 1. Correct me if I'm wrong. [Edit: after some discussion with another team, they proved the answer is 2, so k={0, 1} are the only ones]

At 10 I am also not sure about the correct interpretation, but since it specifies that the balls are numbered and that info is not used later in the problem, I figure it just means that rotations are considered distinct, which would make the answer 12. It isn't made clear in the statement whether rotations are distinct, so it would be nice if someone can confirm which interpretation is correct.
