    Of course, Deep Dark Fantasy, they won in a local contest recently. If there is a gambling, I certainly will bet all on them. ;) I am going to update some information about the teams later.

      How does qualification work? I've seen that Deep Dark Fantasy already won a regional contest. Was that just to get access to this final?

        I don't know, no one know the actually rules this year except Dr. Hwang himself at this very moment, but I still think they must already get the ticket.

Uhm ... shouldn't it be "Chinese" ? I don't think "Chinal" is a correct word.

Why the scoreboard shows teams without rank?

Wish the livestream would just show the screen of Deep Dark Fantasy, instead of just showing view of the room half the time, what a waste.

Nice H! In your blog, you said '09:21 : SJTU Absolute Weapon* solve problem H, they use a better solution than us.' Can you share with us how you and SJTU Absolute Weapon* solve H?

Was the judge server fast? In particular I'm wondering if the following are supposed to pass:

  • O(N2 logN) solution with set for C
  • O(Nlog2 N) solution with set for G
  • O(NlogN) suffix array for F

Also, was it necessary to use BigIntegers in E?

    All of the solutions you described can pass in the contest. It's necessary to use BigIntegers. And Python is supported in the contest.
