I haven't finished it yet, but... I think this kind of clone coding is the real way to study coding. Other clone coding lectures don't explain the code line by line, and they just explain the basic operation principles and the code.. so I was busy just practicing typing. This person explains everything one by one without missing anything.. the kindest of kind. I switched to this after seeing a lecture on PaXX that costs several hundred thousand won, and it's the best. It's perfect for beginners.
