I want to tell you one secret... Actually, when I was writing the announcement, I didn't mean

Wish you quick ideas and short solutions!

I meant

Wish you short ideas and quick solutions!

That was a joke :) But you know there is some truth in every joke. Div1C, Div1E are not the easiest to write code, so maybe that is the main reason why there is no guy, who solved all the tasks.

I had a bad feeling before the contest. I thought there will be many dislikes after the contest. So I disided to collect some statistics about the rating of the announcement post (thanks aleex for script). So here it is (coordinate X indicates the number of minutes passed since the beginning of the contest)

Statistics

As you see, there are some rating fluctuations during the contest, but at the end the rating greately increased. Truly saying I was shocked :)

I am really happy that you generally liked the tasks. So thanks to all who took part in our contest.

If you have any feedback or suggestions, and you didn't share them yet, then you are welcome!

Good day to you, Codeforces!

The problems of this round were developed by markysha, xolm, aleex. That is our first round on Codeforces, and I hope not the last one :)

Thanks everyone who helped with tasks preparation:

I could tell the story how my team trains to go to ACM ICPC (nohow), but it's not interesting)
It is more interesting to learn how to do nothing, but at the same time go to semi-final or final.
So I wonder if there are teams, that didn't train at all, but at the same time participated in semi-final (or were so close to it)? And how did you achieve such success?)

Some time ago I collected useful links from Codeforces, some of them are really cool, some are not.
Dtaft was created about a year ago, now it is June of 2019.
My friend asked me to give him some cool blogs from Codeforces, and I remembered about that blog.
So that is the reason why this blog is posted)
P.S. some blogs are only in russian
