Why unrated?
By __builtin_gjr, history, 12 months ago, In English

I know many people think the problems are bad and want the contest unrated. I lost GM from this round too. But I think the problems are somehow ok. FSTs on A is avoidable, and using long long is actually very obvious. More low rated users FSTed than high rated users, so this is ok and I consider it as part of the problem. BCDEF are good(though I didn't solve E, and also I ignored m<=5000 in F). I know the std for G was wrong at first, but it's fixed quickly, which isn't a big problem. H would also be a good problem, if there isn't oeis. I noticed that many people had passed H when I was doing E, so I tried H in the last 1h. I nearly got the formula in the contest.

Though I still think that authors should at least try to check on oeis before having problems like this, and they should also check for integer overflows for every problem.

Hope to reach GM soon and good luck for everyone :)

Well if you don't agree with me, pls don't downvote me. I wish everyone get their ratings back in Hello 2024(hopefully a good round). :)

    Why i shouldn't downvote if disagree? And I don't think the author didn't solve problem G before the contest "isn't a big problem".

Because D is a ChatGPTable problem?

And someone said that F is as same as a problem in luogu?idk

    D isn't a ChatGPTable problem. It can just give you the answer for small n(which you can also write the code for that part) and then you have to figure at the pattern.

      iirc, for n=11 ChatGPT gives you 99 numbers.

      If you then wanted a solution, for lets say n=30, you would take 30 of these 99 numbers and append 0's to make them length 30.

      But I do agree that this is not a full solution. Its a partial solution to the problem.

        I think that is literally a valid solution. Although it is kinda simple, thinking about inserting the zeroes in the end isn't brain dead.

        Asking chatGPT for 99 numbers is just a different idea, it isn't even the intended solution.

    ChatGPT-able problem doesn't mean it's a bad problem.

    but u will still have to write up the code to make sure the number with 99+ permutations that are claimed to be perfect squares are actually perfect squares.

Actually, round is still rated. Where is it mentioned to be unrated? Upd : Gotcha.. I think so. Still the round had some nice problems and FST is part of the game. After all, my greatest delta is on a 74TrAkToR Div3 (which has been a too nice math force)
