Is it possible to start learning algorithms in a declarative (functional, to be more specific) way?

Question

By algorithms, I mean dynamic programming, greedy algorithms etc.
Almost all of us are probably familiar with imperative programming, which makes things easier when it comes to algorithms.
I just want to learn algorithms and functional programming at the same time, but I can't figure out how to do so.
Or no one would spend time trying that?

Answer 1

If you don't use classes, only functions, then it's already functional programming, because you order all your instructions in functions, which you'll call later. While learning different algorithms, I surprisingly observed that only functions are used - OOP or stuff like that. Check for the Greedy technic or recursivity.

Answer 2

Thanks for your answer, I didn't notice that. I use functions when learning algorithms all the time.
