Hello, Younghan! I am a college student who just finished this basic lecture! I took this lecture after listening to the introductory lecture, but since it was my first time developing and I had no related knowledge, I was worried and lost a lot in the introductory lecture. However, after listening to this basic lecture, I thought, "That's why I did it that way back then~" and I felt like I was gradually understanding it, so I enjoyed the lecture! In fact, from the military until the beginning of this year, I studied algorithms by solving problems on my own for almost 2 years, but from the beginning until now, I always thought, "It would be better if someone taught me rather than knowing everything by myself.. Why can't I?" But while listening to the Spring lecture, you taught me one by one and explained it kindly, so it's great and I think studying is fun~! I really want to get together with my friends and work on a project soon! I dare not know everything, but I thirst for someone to teach me, so I am so grateful that Younghan put a lot of effort into this lecture. It's the best! Although my skills are still lacking, I want to develop as soon as possible, so I plan to take the next lecture as Utilization 1. See you in the next lecture~!
