I liked the detailed explanation. At the national academy, I skipped over this and that, so I just kept copying and pasting, and I had no idea how it worked, so I didn't even know what the code meant or how to find errors. But after listening to the sufficient explanation and understanding it, I looked at it again step by step, and now I think I understand a little bit. Based on the lecture content, I was able to revive the team results that I couldn't even call up because my skills were lacking, and I gained a lot of confidence.
