All the problems below my rating are the best and the problems above my rating which I can't solve are the worst.

    For me, All the problems below my rating are the worst and the problems above my rating which I can currently solve or will be able to solve in the future are the best.

      Yep. That's what differentiate a newbie and a International Master. Top notch mentality .

      All of them. 1921B - Arranging Cats is an extremely complicated one liner. 1207F - Remainder Problem have too low skill levels for a F div2 and requires endl to \n (terrible). With that in mind it barely passes at a badly 3900+ms.

        Your problem on 1207F is not on endl, but this:

        #define int long long

        Seriously, if you cast long long on everything and expect nothing bad to come, even with 64-bit processing support, you would have yourself to blame.

        The problem being surprisingly easy is an odd trait of educational round as a whole, and I would stay neutral at that — neither enjoying nor hating.

        For 1921B, I don't get your point here. The problem is simple as it is. Perhaps skimming and summarizing is something you could do a bit of practice?

          i agree, 1921B is not that hard.

          AkiLotus, what unexpected problems can occur by using #define int long long? As a person, who has that in his template, I would like to know that xd

            In the simplest sense, double arithmetic runtime and/or memory consumption, due to now the CPU has to do maths in 64-bit instead of 32-bit (worse if the compiler itself only supports 32-bit, as it has to do some unnatural twerk to support something higher than it physically possesses).

              i also imagine some functions might have an unexcepted behavior like with __built_clz since it takes in an int, but there is no errors, if you pass in a long long value. thanks

Worst: Zero Quantity Maximization because it doesn't get AC without io sync. Best: White Black Balanced subtrees (loved solving it) and Rudolph and Ball Game

I don't remember all the problems I solved but from the recent problems I solved, a good problem was from ICPC Asia Pacific which is There and back again I had fun solving it and fixing the bugs in my code. and the other was Find a mine it was fun geometry and it's idea was fantastic.

and for the worst, it's not bad but I still remember in Vika and her friends that I have lost brain cells reading the statement and the problem itself was kinda good when someone explained it to me.
