I majored in computer engineering. However, I think that coding in coding tests is quite different from coding in undergraduate courses. Language and algorithm classes in the first and second years of undergraduate school are focused on learning overall concepts, and when doing team projects in the third and fourth years, there is no need to use complex algorithms that are required to solve coding problems. I also had a mental breakdown when I encountered algorithm problems. I had no idea how to solve them. That's why I signed up for this course. The textbook itself was a big weapon. Through the textbook, I memorized the basic functions that are often used in coding tests but have never been used before, and the implementation methods of specific functions. As I listened to the lectures given in class and solved the problems, I felt that my skills were gradually improving. I highly recommend this course even if you only know the basic grammar. Even if you are a little lacking, I think there will be no problem because the instructor answers questions quickly. And as the instructor said, I felt that C++ is good for coding tests. Thank you for the great lecture.
