This open-source project aims to create a free and beginner-friendly crash course for data structures and algorithms.
- Animated illustrations, easy-to-understand content, and a smooth learning curve help beginners explore the "knowledge map" of data structures and algorithms.
- Run code with just one click, helping readers improve their programming skills and understand the working principle of algorithms and the underlying implementation of data structures.
- We encourage readers to help each other. Questions and comments are usually replied to within two days.
If you find this book helpful, please give it a Star :star: to support us, thank you!
