This is the moment I finally properly understood what I was so curious about and wanted to understand when I was attending the bootcamp. Since it was a part I really wanted to understand well, it took me a really long time.. Following your recommendation, I'm listening to Application Part 1, this lecture, and then Application Part 1 again, and I finally feel like the blockage has been cleared. I hope to listen to all the remaining lectures, get a job, and someday meet you, Younghan. Thank you so much for this lecture as well.
