I was impressed by your explanation of how exhaustive search, recursion, and DP are connected in the thought process. I think the advanced lectures are suitable for starting to prepare for coding tests because they cover frequently occurring types that are good to study separately. Something that would be even better is if you could provide a list of more problems to practice, which I think would help with internalization. I haven't completed all the lectures yet, but it would be great if you could share a list of good problems to apply what I've learned!
