is here! Finally, solutions can be spoilered!

For example, my solution to F from CROC 2016 - Elimination Round:

We need LaTeX in spoilers, too.

UPD: Hell yeah, finals! I'll just leave this here.

my solution is also O(M*8505) but it got TLE on pretest #7 :(

constant optimizations sucks, and all problems that have TL more than 3 seconds sucks too

We did not intend for any solution with the constant 8500 to pass. We tried to fail these. The intended solution is , where

I'm amazed that C++ runs so quickly that taking a constant of 8500 passes. Maybe we should have made Q = 2·105, and N = 0 instead.

Our solution will be posted soon.

    But how would you fail 8.5e8 subtractions?

      Not sure, I was just noting that letting this pass was unintended... the constant factor on the other solution was high enough that I think anything substantially less than 8s was too little.

      It doesn't really matter I guess, you should try finding a slightly faster solution anyways. :P

        My solution works 2s without any optimisations. May be 4s time limit will be ok if you add all maxtests in pretests.

    it seems that you need to try out to be a victim of some terrorist attacks in order to understand why refugees are coming to your country.

    instead of offending refugees, why not start to offend countries which are supporting terrorism because if those countries wasn't supporting terrorism there would not be refugees now.

      I'd like to not turn CF comments into political discussion, thank you. We can continue by PM, though.

        Then why you posted that video to public CF?

          He probably doesn't realize honestly that its hurtful to some. I think he didn't mean to offend refugees. I think it was an ill-tasted jest.

        I don't think its easy for Syrians and other refugees to take these satires in good spirit. The rest of the world needs to understand that.

            You're not the only Syrian and you're not the only refugee(if you are a refugee at all) :)

            My point is, its hard for someone who has lost someone very close in a war, or lost their homes, family and such, or just a general patriotic sentiment against war and how people are rendered homeless. Good to know you are still able to take a joke :) It means you haven't lost anything in other peoples' stupid wars.

              I had 2 family members who were fighting in this war. One of them is dead, the other one still is.

              Syrians like Jaddouh don't take jokes not because of the specific horrible situation, but because of the sensitivity culture where emotions are valued more than facts. I can go into more detail but this isn't the place for it. I just want to say that people don't have the right to not to get offended.
