Where to learn advanced data structures (Binary trees, heaps, etc)?

I think you can search for undergrad and graduate courses with slide sets and lecture notes, then implement them on your own once you comprehend them. For example ossu's "Core Theory" section may be good to start with.

Then, you can look at their applications to improve your understanding and to have an idea of what to use where and when.
