Late editorials
By nkamzabek, history, 5 years ago, In English

I noticed that most editorials of the last educational rounds will be published 1 or 2 days after the contest. Of course, I have nothing against it, but at all one trivial question, why?

We have an internal policy that editorials should be published not later than 24 hours after a round. I don't think that writers violate it often.

    But, what about the problems' difficulty ratings update? In some cases, it is updated after 2 or 3 days. I think the difficulty rating is an important feature to know one's progress and it should also be affected within a day or so.

Pffff, is that a problem? If you couldn't solve some task, you can ask me!

      I don't know exact time complexity, but use treap, where every node maintains '2D-Persistent tree with FFT on each node'. To further optimization use meet-in-the-middle, but I don't know how to merge, but at all you can create a graph, after that go to Dominator tree and do some stuffs with combinatorics or Burnside's lemma. But I don't know time complexity.

          Oh, yes. I wasted my 20 years to solve it, but you find solution easier. 10q!
