Curated collection
Algorithms and data structures
Free textbooks and course notes on algorithms, data structures, complexity and the ideas that make programs fast and predictable.
Algorithms are where computer science becomes a discipline rather than a collection of languages. This collection brings together free textbooks and course notes on sorting, searching, graphs, dynamic programming, complexity analysis and the data structures that support them.
Some books are rigorous and proof-heavy; others are practical and code-first. If you are preparing for interviews, pair a general algorithms text with a book that focuses on implementation. If you are following a course, start with the text that matches its syllabus.
The catalog does not rank books by difficulty. Read the description and the publication year, then choose the one that fits your background.
