1. Overview of TreeSet class functions First, the TreeSet class uses the natural order of elements to sort, or according to the Comparator provided when creating the set, depending on the construction method used. We know that the underlying data structure of TreeSet is a red black tree. Let's see how TreeSet ensures the automatic sorting and ...

Inspiration from ziplost to quicklist and then listpack When introducing Redis's optimized design of data structure to improve memory utilization, it mentioned that compressed list (ziplost) can be used to save data. So now you should also know that the biggest feature of ziplost is that it is designed as a memory compact data structure, occup ...

Data structure - sorting notes of arrays and generalized tables (Chapter 6). If there are errors, please correct them. Compressed storage of special matrix Common body type When the number s of non-zero elements in a matrix with large order is very small relative to the total number t of matrix elements, that is, S ...

Dichotomy? Let's look at a very interesting passage first One day Xiao Ming went to the library to borrow N books. When he got out of the library, the alarm sounded, so the security guard stopped Xiao Ming to check which book was not registered for lending. Xiao Ming is going to pass each book under the alarm to find out the book tha ...

Content: Receive a string of message characters from the keyboard and output the corresponding Huffman code. At the same time, it can translate the code string generated by Huffman code and output the corresponding message string. Design requirements:   (1). Construct a Huffman tree;   (2). Implement Huffman coding and d ...

1, Some concepts 1. Bipartite diagram It must not contain odd rings, but may contain rings with even length, not necessarily connected graphsBipartite graph is a special model in graph theory. Let G=(V,E) be an undirected graph. If vertex v can be divided into two disjoint subsets (A,B), and the two vertices i and j associated with each e ...

These three sorts have two-layer cycles, which is their superficial feature. I call the external cycle large cycle and the internal cycle small cycle. Their basic idea of algorithm is the same, that is, the sequence to be sorted is divided into disordered interval and ordered interval. Each large cycle can increase the ordered interval and r ...
