Topcoder bug?
By aid, history, 6 years ago, In English

I encountered strange bug when I tried to solve hard problem from TCO 2017 Semifinal 1(statement). My solution kept getting TL. I spent a lot of time debugging and realised that this TL doesn't depend on my solution. Actually, this simple code which only works on sample cases also gets TL. Why? hmehta, misof please help.

I've encountered the same issue in this problem today. I'm almost sure that it's because the input size is too big in this problem (topcoder limit is around 20,000 characters) and then it's UB in Topcoder. I guess there is nothing they can do about it now.

    Sadly, nobody noticed me that limit.

    And this is too late regret, but now I think reduce coordinate range and count the number of good rects is better. I was too fool, sorry.

    Hey aid, Sorry for the delayed response but yes it's because the input size is too big.

      Thanks for looking into it. I hope such thing won't happen this year.
