Hello CF!
Here's a list of the DSA, in the order I would encourage you to learn them, with some gem tutorials for each:
2) Sorting
4) 2 Pointers & Sliding Window
5) Recursion
10) UFDS/DSU
11) Segment Trees
This is some of the best content out there that I've myself learnt from, taught, and discovered over the years...
Hope you find them useful!
Additionally, EDU is really good when it comes to segtrees.
