    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.

    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:

      1
88 4688 31 4 88

      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.
