hello-algo

Hello Algorithm (Hello Algorithm) is an open-source data structures and algorithms tutorial designed for beginners, maintained by krahets. The project aims to help readers easily master core knowledge of data structures and algorithms through intuitive animated illustrations and one-click runnable code examples. Key Features: - Animated Illustrations: The entire book uses animated forms to display algorithm execution processes, making content clear and easy to understand with a smooth learning curve, guiding beginners to explore the knowledge map of data structures and algorithms. - One-Click Run: All source code can be directly executed, helping readers improve programming skills through practice and gain a deeper understanding of how algorithms work and the underlying implementation of data structures. - Multi-language Support: The tutorial text supports five languages: Simplified Chinese, Traditional Chinese, English, Japanese, and Russian; the code implementation covers fourteen programming languages including Python, Java, C++, C, C#, JavaScript, Go, Swift, Rust, Ruby, Kotlin, TypeScript, and Dart. - Collaborative Learning: Readers are encouraged to ask questions and share insights in the community comment section to make progress together. The content covers introductory knowledge of data structures and algorithms, including arrays, linked lists, stacks, queues, trees, graphs, sorting, and searching, making it suitable for programming beginners to study systematically. The project is continuously updated, and contributions to content corrections, code translations, and multilingual translation reviews are welcome.
