I am very satisfied. 1. You review your code with me to see which parts are strange. Usually, since you write your own code, you may think that you have handled all the error situations that you can think of, but there may be parts that you missed. And it takes a lot of time to find those parts, so you may give up. When that happens, if you tell the instructor, he will review it with you, so you can see which parts you missed, and thanks to that, your perspective on various situations broadens. 2. You can get an approach to solving the problem. There are problems where you just can't figure out how to start when you see the problem. In those cases, it seems good to quickly learn how to approach it by looking at the instructor's solution. 3. In addition, you can learn how to use various functions, which ones take a long time, etc., so I am very satisfied.
