3 Points to me right now — You were close but sorry you can't make it. :sadness:
Editorial draft is here.
(The proof for the div1 1000 will be added later, as it requires also adding a bit of the background on this type of games and I didn't finish it in time. I'll update this post once it's complete.)
You forgot to give access :)
Yes, I copied the wrong link :D Thanks for the reminder, should be fixed now.
Can you please mention few problems like today's div2 300 that are very observational based from topcoder/cf round I found these problem very complicated even though they have a naive solution?
