TheAlgorithms/Algorithms-Explanation

Coding Interview University is a GitHub repository maintained under the jwasham account that lays out a checklist-based study plan for the computer science fundamentals a software engineering interview tests. It covers sorting, trees, and graphs as a required track, then an explicitly optional back half on system design and extra tree structures for engineers with more experience. The README frames it as the author's own multi-month self-study process, later published for others to follow, and community members have translated it into multiple languages.

trekhleb/javascript-algorithms is a GitHub repository of JavaScript implementations of well-known algorithms and data structures, with 196,457 stars and 31,041 forks under an MIT license. Every entry gets a dedicated README explaining it, and the collection is cross-referenced by data structure, by algorithm topic, and by algorithmic paradigm such as backtracking or divide and conquer.

The Algorithms - Python is an open-source collection of algorithm implementations written in Python, maintained by the TheAlgorithms organization on GitHub. The README frames the whole project as a teaching resource: the code exists to illustrate concepts, can run slower than Python's built-in equivalents, and is indexed in DIRECTORY.md for browsing. It's MIT licensed and has 223,712 stars and 50,966 forks on GitHub.

EbookFoundation/free-programming-books is a community-maintained collection of freely available programming learning resources, initially a clone of a StackOverflow list. Now administered by the Free Ebook Foundation, this repository, which has accumulated 394309 stars, organizes content into categories like books (sorted by programming language and subject), cheat sheets, online courses, interactive tutorials, problem sets, podcasts, screencasts, and programming playgrounds. A significant feature is its extensive multilingual support, offering resources in dozens of languages. The project is licensed under CC-BY-4.0 and actively encourages community contributions to expand its offerings.
