Congratulation to div 2 winner TadijaSebez — Serbia is proud of you !
Thanks all for participation ! You made this contest amazing !
I hope, this time difficulty level will be easier than some previous cook offs.
I really hope it will be more balanced by amount of AC than previous rounds :)
Obviously I wasn't right. Hack Fulu is much harder than we expected. I am really sorry for it, but I hope you find something interesting in tasks :)
Yeah. But I think I had seen that GUZAC problem somewhere else. Maybe I will find that link ASAP and send it to you.
Contest is starting for 3 minutes !
The first div0 round ;)

How to solve the problem Standard Tree Task ?
No one would have expected this solution for the toughest problem of a cookoff. xD

At least nobody got AC on that way during the contest.
I am not sure how did it pass. I believe it is problem with language time limit of problem and it should be solved for next contests by Codechef! We tested problem pretty much and I am sure that total brute force is not even close to pass on current data.
Also your solution for HACKFU is giving wrong output for many cases. For example:
It's failed with almost the first random test! Is it also been tested pretty much ?
Actually the correct story is next:
I had bug in my frist solution when I generated testcases(that solution). Then tester noticed it and I changed code and test-data. But we didn't rejudged all previous submissions (because I only had one AC), so editorialist saw AC and added first code because it is more clear than my second.
For better understanding all this stuffs happened before round :)
I will ask him to change it. Sorry for our mistake.
PS: That solution must give WA if you test it on CodeChef.
Btw, thanks for the problems, I enjoyed a lot. I just want to point this moment to you, so you be more carefully next time.
