I learned a lot about algorithm concepts.

Sigh... I shouldn't have included the keyword "algorithm"... This is really... Honestly, isn't this too much... As the difficulty increases towards the end, the supporting content is way too shoddy. Even if you're going to half-ass it, there should be limits... This is really too much... Moreover, some of the video materials are missing algorithm solutions. I seriously wonder if it's okay to charge money for this... It's that bad...

I listened well.

It feels like the instructor has taught many other people. Firstly, the algorithm lecture order feels the most correct. Thank you for the good lecture.
