Hey! i just gave my first codeforces contest yesterday, I have done a little bit of cp on platforms like leetcode and codechef earlier this year, but it feels nice to start coding on this platform.

I have covered basic topics like math, constructive algos, and implementation. I wish to learn the advanced topics like graphs, dp and trees. Will it be advisable to do those from here or another platform/youtube tutorial/course?

Any leads/advice will be very much appreciated :)
