On the other hand, 51 pretests in div1D could've been cut down by (well selected) 50% or more with only benefits.

    This problem is classical, the point was that they made it interactive so that only logarithmic solutions can pass.

      This should have been a problem for education round and not a normal one.

      Many users like me don't know about this. I have to work on it for around 40 mins to come up with the solution, whereas many users might have just googled it and would have solved it within 10 mins. Don't you think this is unfair for those who didn't search for the answers on internet, are at a loss. The point is that they should not copy exactly the same question available in geekforgeeks. It can be some variation of it.

I think half of Div2C solutions got hacked. There were ~3700 solves before system testing and after only 1700.

    Likely because of wrong comparison.

Stupid system tests also. Many solutions like this, this, this, this should fail on :-
