I am a first-year backend developer in a non-major program at a national university. Thanks to this, I was able to get a sense of direction on which sections to focus on and which parts to study first before studying in-depth CS knowledge. The lecture itself is targeted at CS interviews, so I personally skimmed through it once and figured out what to study first, but it is not that the lecture is shallow. There were many parts I didn't know, and I was able to flesh out the parts I already knew. In addition, I asked a question that was off-topic because it overlapped with the part I was studying on my own, and I would like to thank Bigdol for kindly answering me by providing me with foreign documents.
