Confusion in what to choose

I am doing programming for a while and I feel like I should practice more…
I think I should learn more concepts. Can anyone suggest a platform where we can solve problems according to their category?
suppose say I wanna learn trees then can I pinpoint them and solve similar problems.
thanks in advance.

You can tryout the practice section of hackerearth.
Here is the link:https://www.hackerearth.com/practice/
It will make you understand the concept first by a concise tutorial and then based upon that there are problems starting from beginner level.
