I have seen many algorithm books and algorithm lectures because the introductions looked good, or the course reviews looked good, or the preview lectures looked good. Then, in the middle, there were always cases where I thought, "Huh? Why is this written like this? What does this mean? How does this work?" (It's not that those things are all bad, but sometimes the explanations are insufficient.) Then, there were times when I got distant from the algorithm. Of course, I couldn't listen to the latter half, so I can't guarantee, but I don't think this lecture will be like that. There doesn't seem to be a single part lacking in the explanation of the concept, implementation, or operation method (for me). So far, I think this is the most friendly lecture in terms of explanation among the algorithm-related books and lectures (by my standards). 👍🏻
