It would be great to reschedule this round, because it intersects with Venture Cup.

    Codechef contests have a fixed, known schedule, so they just do not get moved.

      So they will continue to attract less and less participants. The quality of the latest contests on codechef (specifically Cook-offs) definitely shows that codechef should adjust to CF, but not the other side.

      It's a pity that the contest from a promising writer will have so few participants.

        Well, as far as suddenly starting to move contests after years of fixed schedule goes, I'd expect that to make a lot more people angry than happy.

        In the end, Russia>>India anyway.

        UPD: Heh, it looks like I made a bunch of people angry. Well, pride in one's country is not a bad thing — if only Europeans had more of it...

                Seriously? You think he's racist for stating the facts?
                Compare the ratings of India and Russia.

                Not convinced yet? Lets have a look at ACM ICPC wins here. Russia has 11 gold medals and we havent even come in top 10 yet.

                Instead of Blind Nationalism, just accept the fact that we are behind and instead work on improving ourselves rather than cursing others for stating the facts.

          I think he meant the number of programmers that will take part in one round(more russian participants on CF) or the other(more indian participants on CC). I am from India too, but please keep the community sane!

          Me, reading Xellos' comment:

          "Well, as far as suddenly starting to move contests after years of fixed schedule goes, I'd expect that to make a lot more people angry than happy."

          so far, so good...

          "In the end, Russia>>India anyway."

          Now you fucked up!

          "UPD: Heh, it looks like I made a bunch of people angry. Well, pride in one's country is not a bad thing "

          so far, so good...

          "— if only Europeans had more of it..."

          You just fucked up again. As a refugee, I feel offended.

Deletable problems… We won't be able to enjoy the delectation of problems if they're to be deleted :\ (UPD: The typo is fixed, thanks!)

Last two problems... I expected them to have step 1: write a bruteforce and see a pattern, and it really was like that.
