Teacher Hao Bin’s is very good.

He talks very well. Teacher Hao Bin’s thinking is based on the beginner’s thinking, which is very suitable for beginners. Basically, he will explain in detail any questions you don’t understand. What he taught was not very comprehensive, but it was quite profound. The book used in the course is "Data Structure" by Yan Weimin, which may be difficult to understand. You can check out "Dahua Data Structure" or "Aha!" Algorithms" two books.

I believe that both those who have graduated and those who are currently studying in school have been tortured by the course of data structure and algorithm to a greater or lesser extent. The course on Data Structures and Algorithms talks about a very important concept at the beginning: Program = Data Structure + Algorithm. Beginners may not be able to fully understand this sentence, but for students who have been working for two or three years, I believe this sentence is correct. The words are firmly believed.

Three steps:

1. First, first have a general understanding of what an algorithm is. You can get started by reading some popular science books. I call this process the entry stage;

2. Then you can try to implement some easier data structures and algorithms, so that you can have a deeper understanding of data structures and algorithms. I call this process the practice stage;

3. Finally To understand the relevant mathematical principles behind data structures and algorithms, etc. I call this process the principle stage.
