I am taking the course by first solving the problems in the book and then reviewing them! When I took the course directly on the YouTube channel, it was difficult to manage my course history, but now that it is also on Inflearn, I am taking the course much more comfortably! ㅎㅎ Unlike other books or lectures, I think the process of solving all the problems by hand and the explanation of pseudo code are what differentiates it, and thanks to that, it is much easier to understand. I recommend that those who study from the book also watch the lecture. Even if I thought I already understood it, I was able to review and understand it more deeply by listening to the lecture. The only regret is that the lecture does not cover all the problems, but the explanation in the book is detailed, and I am very satisfied with the fact that this quality lecture is provided for free. Thank you, Harucoding, for the great lecture.
