If you are a major, it will be easier!! * An instructor who gives good feedback on questions and even answers them if you wait I wonder if there is anything better than this.. ** The class and workbook are conducted while also providing an overall strategy ex) Think for 2 hours and study the solution after that *** A C++ knowledge book for those who are new to C++ or have already been exposed to it, for coding ex) Algorithm textbook.. If you master this, you will probably be able to solve any problem that is not really difficult. Overall) I think it is a miracle that you can access such sincere content at this price. Seriously, what I think is... I wish other friends wouldn't buy it. I want to be the only one who gets the benefits... But if that were the case, the world wouldn't develop ㅠ p.s) It's also fun to watch the instructor's YouTuber
