Hey everyone!

Dear all, we remind you that today at 18 PM the second division of ABBYY Cup 2.0 starts!

There will be a special problem from Codeforces as a present for participants!

The duration of the contest is the same. You should solve seven problems in four hours. The tests are split into two categories (easy and difficult), they are worth 30 and 70 points, respectively. Only fully passing a group of tests is counted. When contestants win the same number of points, the penalty time is counted by the ACM rules. Fully solving some group of tests is counted as submitting an ACM-problem and will determine the penalty time you get. As MikeMirzayanov commented:

The second division (easy) contest will be a rated event for Div. 2 Codeforces users, so it will be rated for official participants and those unofficials who is from the Codeforces Div. 2.

These contests are officially available to those who is included in the Codeforces’ second division. The Codeforces’ first division users can take part in the second division out of competition.

Good luck!

Very enjoyable contest for me :)

Just one question: Was my idea for Space Voyage correct? What I did was perform a binary search for the lower and upper bounds of X (of course, only if it was confirmed that there weren't infinite solutions). My rightmost bound for the BS was c * MAX(b[i]), and I got WA on test ~ 23 or so.

    Yes, that's a correct solution. It's very easy to overflow though (the problem statement even hints at this).

    The second division (easy) contest will be a rated event for Div. 2 Codeforces users, so it will be rated for official participants and those unofficials who is from the Codeforces Div. 2.
    Again :
    It will be rated for official participants and those unofficials who is from the Codeforces Div. 2.
    One more:
    And those unofficials who is from the Codeforces Div. 2.

    The standings include results from both divisions where as the contest results only consider Div-2 contestants.

    To see the results for a single division (and therefore the results for the Div-2 contest) you can select Div-2 from the top-right pulldown menu.

    Unofficials include Div1 contestants, but rating change only in Div2.

All tasks were enjoyable, one of the best competitions recently. :)

The solution for task G must be ingenious because of the constraints. Any ideas?

    These problems are not supported in practice correctly for now. I've temporary removed them from the problem archive. Sorry.

To Mike: My rank in Abbyy Easy is 80 and I solved 4 questions correctly. But my rating change -10 and my rank is 199 in the contests page of my user. If I tick the show unofficial my rank is 269, too. WHY?????

    As mentioned in earlier comments: select "Div-2" in the top-right pulldown menu. Overall results include Div-1 as well. As for your rating change: consult the FAQ.
