In the National Day, I want to end the review and self-test of the data structure. As a result, the progress of the progress is slower than my imagination until the No. 5 is reviewed. Helpless, have to continue, continue to work. Being a review to complete the review, you have to learn the operating system and composition principle. There is also a review, compilation, compilation, and internship of data structure and C . This study is prepared to end C , operating system, composition principles, compilation, probability theory, and have a heavy task. There is a saying that "Chinese people are not afraid, what are they afraid?" Said good! Fight, otherwise how to get the revolutionary martyrower of the throwing head sprinkled with blood, huh. Try Harder!
