I struggle to even understand those problems, I checked a lot of 1000-1200 graphs tasks, and I just don't understand them. https://mirror.codeforces.com/problemset/problem/2078/B

and the solution for that issue it is not understable for me.

A lot of the times, I read the problem, I don't understand fully the problem, the only problem I solved in that range is this one. not sure why it is 1100 https://mirror.codeforces.com/contest/1829/problem/E

those problems are pretty difficult even if they are low rated.

higher rated ones are looking very crazy, with I can't imagine what type of person even solves this. (above 2000)

who is even using that website, those people who go to math olimpiads? what is the target audience?

16 year old prodigies, what whole personality is math and coding?

this website really has this vibe, be very smart or get lost.
