What you want to ask is what if the university search software can't find the topic? Read the book a few times, or you can ask the teacher to discuss your ideas.

If you can't do the problem, you usually don't understand the book knowledge thoroughly enough. Read more books and find out the knowledge points. If not, please ask the teacher to explore ideas and then solve the problem.

University search software includes: Baidu Smart Classroom, Netease Cloud Classroom, University Search Sauce, Online Course Answer Pro, Momobei Dialect, Geek College, etc.
