Please don't make problem A hard
By GoBack, 19 months ago, In English

If problem A itself is very hard then many participants will not even participant in the contest because of fear of loosing rating.
And because of that number of participants is too less than than the number of participants registered for the contest.
And it will affect the overall rating of many users. (Obviously who atleast solved A should have higher ranking than the one who not even solved A , but according to current scheme if user not made any submission that means user is no more participant for that contest.)
Make problem A very easy so that they do atleast one submission for the contest.
What's your thought on this point ?
Thank you.

Indeed. This time A was so much harder. On average I solve problem A in like 4 minutes but this time it took me 15. It really has a big effect on the number of participants. I have never seen a round with only around 5000 participants.

OR They could add a rated/unrated register option like AtCoder.

          Look at your comment list, and yourself. Making an entire account just to insult people because you are too scared of actually insulting them from your main account. God save Codeforces.

          After all this "rated/unr participant" comment is very useful.Please don't judge cmments with their posters.

      you know that's the best solution. You can't tell problem setters every time not to make hard A. But if there is an option for rated/unrated participation you can still enjoy the contest if you feel too hard.

      I can't believe you opened a new account just 3 hours ago to write those shits!!!

        Yes that's the best solution. But he(Your_comment_is_useless) write those only because the comment's writer(chromate00);And he already knew those will get much downvotes so he created a temp account,I can't understand.

Friendly advice Never attend contest set up by 74TrAkToR. Because they are always with mathematical problems and observations in them

    What is wrong with a mathematical contest with observations?

Not only that, today most people participated in 1st contest and were too tired to participate again, like myself

    Then don't participate in the second one, what is the problem? These rounds were based on olympiads, so likely moving them was not an option. Featuring both of these contests is still strictly better than featuring only one.

      I know and I'm not against that, I just mean that this wasn't the only factor about today's contest

It also harms the problem ratings.

Read the whole blog

I agree that Problem A should be easier; it also boosts the morale of the participants.

In the last round A was really hard. Anyway, I believe that the rules need to be changed: for those who have opened and read at least one task, they should already be considered as participants, so that there is no temptation to skip the competition.

Usually, div2A and div2B can be bruteforced as problem setters tend to lower the limited for arrays sizes, and every now and then I get stuck and frustrated trying to solve them, so I find myself writing some brute force with some DP if needed for such problems, check out my solution for the last A problem, it's probably bad advice to avoid the intended solution in favor of the dump bruteforce one, but sometimes it can save the day.

Just grind on the problemset man. Eventually you will become good.
