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.
I've only included video tutorials as it's intended for beginners. Ofc nothing compares to CF blogs
EDU ITMO course is packed with videos as well as implementation (+problems). I think it might be the best place to start. You should check it out.
Oh thanks for sharing
