An open-source, beginner-friendly book teaching data structures and algorithms with animated illustrations and instantly runnable code examples. It is available in multiple languages (Chinese, English, Japanese, Russian) with implementations in 13+ programming languages.
Use cases
- learn data structures and algorithms from scratch
- prepare for coding interviews and leetcode practice
- see algorithm implementations in my favorite programming language
- find a free alternative to paid DSA textbooks
- understand algorithms visually with animations
- run tutorial code examples locally while learning
When to choose
- you are a beginner wanting a gentle, visual introduction to DSA
- you want runnable code examples in many languages
- you prefer a free, open-source book with active community support
When to avoid
- you need an exhaustive advanced algorithms reference (e.g., CLRS-level depth)
- you need a runnable library to import into production code
- you require a formally licensed resource (license is non-standard)
