Thank you for the great review, Bak-ryeok! Your active approach to studying while thinking things through yourself is an excellent attitude! And actually, about 90% of the code I write in the lectures is prepared in advance 😊😊😊 The remaining 10% comes from filling in gaps that seem lacking while recording with live coding. I set the general direction within a broad framework and proceed according to the flow of thought, but I'm glancing at the side monitor while writing. If you observe the mouse pointer carefully, you'll see it moving to the side of the screen 😆😆 Also, naturally, I can't create clean and efficient code from the start either - I continuously revise and improve the written code. Of course, as you write code frequently and become proficient, the overall structure quickly forms in your mind, intermediate steps are significantly shortened, and your speed increases dramatically. Ultimately, it's also a matter of adaptation and mastery, so you don't need to be too anxious right now! If you continue developing alongside your studies, the day will come when you'll do great. Read some object-oriented programming books, practice with them, and solve lots of algorithm problems - you'll feel it soon! There are opinions that algorithms aren't necessary these days because of AI... but setting aside coding tests and competitions, they're very effective for developing efficient implementation skills and problem-solving abilities. Anyway, great job completing the course! Keep it up!
