Wouldn’t it be great if questions in long challenge have prerequisites mentioned while the conest is running. Most of us solve long challenge so that we can learn new things.
Suppose there’s a question that can only be solved using FFT and there are many people who haven’t even heard of it. So they get stuck at that problem and think for many days which isn’t going to be productive at all.
Now many of you may say it’s like giving direct hint to the problem . Yeah I agree, but we are atleast learning something new in that period.
There’s an other way to do this. In the long challenge announcement itself they can mention prerequisites to solve this long challenge.
AUG 20A prerequisites : Binary search, Segment Tree, Lazy propagation, FFT …etc.
What do you guys think about it ?
