Data structure is the way computers store and organize data. A data structure refers to a collection of data elements that have one or more specific relationships with each other. Often, carefully selected data structures can lead to higher operating or storage efficiency. Data structures are often related to efficient retrieval algorithms and indexing techniques.

attrs and cattrs: Tutorial for elegantly handling nested data structures

05 Aug 2025

This tutorial explains in detail how to use Python's attrs and cattrs libraries to efficiently handle nested data structures, especially converting complex data containing dictionary lists into attrs-defined lists of class instances. The article will explain the limitations of the attrs built-in converter and demonstrate how cattrs can automatically and gracefully map from raw dictionary data to complex attrs objects through its powerful structured capabilities, simplifying code and improving maintainability.

PHP Master | Data Structures for PHP Devs: Heaps

23 Feb 2025

This article introduces heaps, a specialized tree-like data structure closely related to stacks, queues, and trees. Heaps maintain the heap property: a parent node's value is always ordered relative to its children's values. Key concepts include ma

PHP Master | Data Structures for PHP Devs: Graphs

23 Feb 2025

Key Takeaways Graphs are mathematical constructs used to model relationships between key/value pairs and have numerous real-world applications such as network optimization, traffic routing, and social network analysis. They are made up of vertices

PHP Master | Data Structures for PHP Devs: Trees

23 Feb 2025

This article introduces tree data structures in PHP, focusing on their hierarchical nature and efficiency in searching and sorting. It builds upon a previous article covering stacks and queues. Key Concepts: Hierarchical Data: PHP tree structures r

C tutorial for data structures and algorithms

26 Jun 2025

When learning C's data structure and algorithm, you should first master the STL container, then start to implement the infrastructure, then learn common algorithm ideas, and finally consolidate them through the question. First, be familiar with STL containers such as vector, list, stack, etc., which are used to simplify code and solve common problems such as the sum of two numbers; second, manually implement the structure of arrays, linked lists, stacks, queues, binary trees and graphs to deepen the underlying understanding; then learn algorithms such as sorting, searching, recursion, dynamic programming, greed and graph theory, and combine C characteristics to implement them, such as using queue to implement BFS; finally, use LeetCode, Niuke.com and other platforms to practice questions and debug more to improve practical capabilities.
