I listened to a good lecture. I would like to tell other students that if you want to learn in detail, please take another lecture. I listened to this lecture in a review format after already listening to the detailed part. However, you can follow and understand it simply by listening to this lecture. However, the most important point here is the example materials containing know-how rather than the lecture, and it is also very meaningful that I only received materials that I really wanted to have. I listened to a good lecture. Thank you.
