#discuss Which is the best online LIVE course out there for learning DATA STRUCTURES & ALGORITHMS?

I wanted to dedicate this month to learning Data Structures and Algorithms. Sadly, I can't find the right course for it.
I searched for some courses in Udemy and Udacity but I did not find anthing satisfying.

Does anyone have any recommedations for this one?

I would be happy if you could tell me which course you took for learning DSA.
