SICP the book is free online.
MIT open courseware classes, as well as UC open courseware classes. Khan academy has good resources as well.
If you want to get super geeky, the art of computer programming. But it’s a dense read
SCIP is great and completely worth reading, but it’s not really a data structures book, and while it has various algorithms in it, it’s not really that similar to an algorithms book either.
It was intended more as a CS 101 book than as either an algorithms course or a data structure course.
True but it’s a nice gentle introduction to both data structures and algorithms.
Which seems to be the core question here.
I haven’t taken it myself, but “The Last Algorithms Course You’ll Need” is free and is written by The Primeagen. He works at Netflix and runs a programming-focused YouTube channel, and as far as I can tell is very knowledgeable and level-headed.
