First of all, I am glad that the lecture is clean and good. How to apply for class materials permission and tips for using them <--- I made this video separately and explained in detail how to download the coding project files in their entirety. I am giving you permission to view very detailed documents, and I also explain in detail how to apply for this part in the video. Haha, no, in cases like this where you say something contradictory, hahaha, I will first understand that you unintentionally wrote a false course review. It would be better if you corrected the parts that were not true. Nevertheless, I will take comfort in that you said that it is clean and good.
