Another vote for Tim Roughgarden’s work. As someone who recently became a software engineer without a cs degree, his Stanford Algorithms I & II lectures (similar content to his books) have been the best instruction I’ve had on DS&A. I’ve dabbled with Skiena’s book, Grokking Algorithms, CTCI, and I now also have a copy CLRS that I use for reference or to go deeper on certain things. But I revisit Tim’s work all the time. Can’t recommend him enough.
