Beware of the Cormen et al "Introduction to Algorithms". It's a good book. But while it says "introduction", it's typically used for like a third-year undergrad who has a fair amount of programming, data structures, and algorithm experience already. It's more about algorithm _analysis_ - that is, how to prove things about algorithms and formally establish their run-time/complexity bounds - than about how to use or write them. Probably not what you want to start with.

Knuth's Art of Computer Programming is even more hardcore than that, imho. Probably not what a beginner wants unless you want to dive right in to the deep end.

SICP is more accessible but still pretty textbook-y.

But I don't actually know what I'd recommend instead. I did a CS undergrad degree, so Cormen and other textbooks are how I learned. But I did that over 5 years with lots of professional help. Dunno what a good self-study-friendly alternative is.
