implement an ordered set key. There is also an internal data structure used in the cluster node.Redis's jump table implementation consists of zskiplist and zskiplistnode two structures, in which zskiplist is used to hold the information of the jumping table (such as the table Head node, footer node, length). The Zskiplistnode is used to represent the jumping table node.Integer collectionAn integer collecti

Meaning of data structureBefore we learn the data structure, we first understand the meaning of the data structure. A data structure is a collection of elements that are organized in a way, such as numbering elements, that can be numbers or characters, or even other data

follows:Set table total n nodes, divided into B block, s=n/b(Block Lookup Index Table) average lookup length =log2 (n/s+1) +S/2(Sequential Lookup Index Table) Average lookup length = (s2+2s+n)/(2S)Note:The advantage of block lookups is that when you insert or delete a record in a table, you can insert or delete operations in the block (because they are unordered in the block, so you do not need to move a lot of records) as long as you find the block that the record belongs to. The main cost is

different element, thus S (i) s (j) = NULL, which makes these collections disjoint (disjoint). There are two operations that can be performed, that is, finding the collection to which a given element belongs and merging two collections. An operation is find, which returns the name of the collection that contains the given element (that is, the equivalence class). Ling An operation is to add a relationship. If we want to add relationship a~b, we first need to know if A and B already exist. Thi

The kernel uses three data structures to represent open files, namely the File descriptor table, the file table, and the V-node tables. The relationship between them determines the possible impact a process might have on another process in terms of file sharing. Each process has a record entry in the process table, and the record entry contains an open file descriptor table, with each descriptor oc

Data structures in PythonHere's a summary of the built-in data structures in Python (built-in data Structure): lists, tuple tuples, dictionary dict, set set, covers only some of the focus, detailed to describe each knowledge point is not involved.Notable features of List lis

From here, we will be explaining the Java data structure, is it ready? Let ' s go~~The data structure model in Java can be divided into several parts:1. Linear structure2. Tree-shaped structure3. Graphic or mesh structureIn the next few chapters, we will explain these data structures separately, mainly through the way

JavaScript implementation Series for common data structures Stack Queue Linked list Collection Dictionary Hash table Two-fork Tree Figure Front End and data structure The data structure is a kind of refinement of the programming idea in the development, there is no about which language dev

stacks and queues?A: This depends on whether you can accurately predict the amount of data the stack or queue needs to hold. If this is not very clear, the list is more suitable than the array. Both are fast, so speed may not be the focus of consideration.Q: What is an abstract data type (ADT)?A: In a nutshell, it's a way of thinking about data

Linear tables, linked lists, and hash tables are common data structures. During Java Development, JDK provides a series of corresponding classes for us to implement basic data structures. These classes are in the Java. util package. This article attempts to explain the functions of each class and how to use these class

Next I'll try to use JavaScript to implement common data structures, and write stacks today.The first thing we need to know is that the stack is an ordered set that follows the last-in, first-out (LIFO) principle. The newly added or deleted elements are saved at the end of the stack, called the top of the stack, and the other end is called the bottom of the stack. In the stack, the new elements are near the

Before you start decoding, you must first understand the important functions and data structures in FFMPEG. 1. Data Structure: (1) avformatcontext Avformatcontext is a persistent data structure. Many functions use it as a parameter. The comment on this data structure in FFMP

the process data in the lookup table is a change, there is a delete or insert operationBinary sort tree: The structure of a tree is usually not generated at once, but in the process of finding it, inserting it when there is no keyword equal to the given node in the tree. The characteristic is that the root node is larger than the left child, smaller than the right child. You can modify the pointer based on the node location when you delete the

This implementation of the data structure is about the expression and implementation of the string, first of all, the heap allocation storage representation and implementation, the following blog will post a string of additional data structure representation and implementationHeapstring.h file data structure body, as follows#ifndef _heapsring_h_#define _heapsring

Parent representation (sequential storage structure) 用一组连续的存储空间来存储树的结点，同时在每个结点中附加一个指示器(整数域) ，用以指示双亲结点的位置(下标值) 。数组元素及数组的类型定义如下：＃define MAX_SIZE 100typedef struct PTNode{ ElemType data ;int parent ;}PTNode ;typedef struct{ PTNode Nodes[MAX_SIZE] ;int root; /* 根结点位置 */int num ; /* 结点数 */ }Ptree ;Shown is the storage structure represented by a tree and its parents. This storage structure takes advantage of the unique nature of the
