(This book takes a computer teacher's teaching as the scene to explain the knowledge of data frames and related algorithms. The whole article is described in an interesting way. Many of them refer to all kinds of day knowledge for analogy, and make full use of graphic language to give play to the general content. Some classical algorithms involved in the data framework are analyzed line by line and compared with multiple algorithms. Compared with similar data framework books on the market, this book is easy to read, with detailed and profound algorithm explanations. It is a very suitable self-learning book)
