Here, the Nebula wish you a successful final exam, Happy New Year! Introduction to the first chapter1. Data structure is a study of non-numerical computing progra

9.10 Summary Review The content of this chapter is just sorting, we need to compare the various sorting algorithms already mentioned to summarize the review.First we talked about the definition of sorting, and mentioned the stability of the sort, which is critical to some special requirements, so we need to pay attention to the stability of the algorithm in the sort algorithm.We will sort the records are all placed in memory, the sorting is divided in

Sort: Sorts a sequence of objects according to a keyword; Stability: If A is originally in front of B, while A=b, A is still in front of B; Instability: If A is originally in front of B, and A=b, then a may appear behind B; Sort within: All sorting operations are done in memory; Out of order: Because the data is too large, so the data is placed on the disk, and the sorting through the disk and memory

After six years in college, I will have a master's degree next year. At this time, I began to review the data structure. What is a data structure? According to the explanation of an authoritative expert, data structure + algorithm = programming, which in turn understands that data
