Hello, this is instructor Baekoblin. First, I would like to apologize for any inconvenience to the students. There was a change in the code between the time of the lecture and the middle of the lecture, so I temporarily stopped sharing the lecture materials and source code to reflect the relevant part. However, the upload was significantly delayed due to the overlapping schedule of the wedding and honeymoon. I would like to apologize again for any inconvenience to the students due to personal reasons. I am currently back in Korea and working on it again. I will share it again as soon as possible. Thank you. Instructor Baekoblin.
