I did not review the data structure in my freshman year. I was despised during the interview. When I saw a senior student, it should be the test question of Kingsoft: To a matrix,

I have always believed that it is always best to learn about any new technology and the excellent books related to it. Of course, a good video tutorial can help you get to know the technology quickly, but to learn the technology in depth and in a systematic way, the best books are especially important. In combination with my own experience and lessons learned from Java, I make a list of some good books I've seen, which is my suggested reading order.1. The first
