Hello sir ! As summer is almost over, I made it with the feeling of a hoorr. It was my last assignment, so I said I was working hard, but I'm not sure if it was expressed well Thank you so much for the lecture! This seems to extend the range of tools available. If you have another class, I would like to register right away.Thank you so much. I'll review it hard for the rest of the class. Haha The weather suddenly got cold. Watch out for colds and corona!!
