Depth-first search of directed graphs and dynamic selection algorithm of adjacency matrix
Introduction In graph theory, a directed graph is a graph structure with directional relationships between nodes. In practical applications, we often need to represent and operate directed graphs. In order to improve efficiency, we can dynamically select appropriate data structures for representation based on the size of the graph and the frequency of operations. Adjacency […]
Data Structure-Linear Table-In-depth explanation
Linear table Array Concept: An array (Array) is an ordered collection composed of a limited number of variables of the same type. Each variable in the array is called element. Array subscripts start from zero. Arrays use a contiguous memory space to store a set of data of the same type. Time complexity: Reading and […]
@CreateCache: In-depth analysis of its functions and advantages
1. Preface to @CreateCache In modern web application development, caching is one of the important means to improve performance and response speed. The @CreateCache annotation is an annotation used to create caches in the JetCache framework. This article will introduce the @CreateCache annotation and its role in cache management. 2. @CreateCache usage example The following […]
In-depth OpenCV Android application development
Preface OpenCV is the abbreviation of Open Source Computer Vision library (open source computer vision library). It is the most widely used computer vision library. Opencv is a collection of commonly used operating functions in the field of computer vision. It is written in C/C++ and also provides encapsulation of Python, Java and any JVM […]
JAVA converts List into Tree structure data and depth-first traversal
Introduction: In daily development, we often encounter the need to convert the data returned from the database into a tree structure, or need to bind the hierarchical relationship of the data converted into the tree structure and then return it. For example, we need to count the number of data under the current node. How […]

An in-depth explanation of data binding validation in WPF
In-depth explanation of data binding verification in WPF WPF provides a verification function when the user inputs. Usually verification is implemented in the following two ways: Throws an error in the data object. Usually an exception is thrown during property setting, or the INotifyDataErrorInfo or IDataErrorInfo interface is implemented in the data class. Define validation […]
In-depth analysis of Flink: source code interpretation, data tilt code implementation
Hello everyone, I am the Great Sage, and I am very happy to meet you again. In the last article, we discussed in detail how to solve data skew by making each parallel subtask of Flink have a corresponding key. However, we have only talked about the idea and design understanding of this solution, and […]
