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.

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.

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.

CS-Notes is a GitHub repository maintained by CyC2018 that collects Chinese-language study notes across ten topic areas: algorithms, operating systems, networking, object-oriented design, databases, Java, system design, tools, coding practice, and an afterword. It links each topic to standalone markdown files instead of writing everything inline, and the README says most of the content is original work rather than material copied from elsewhere.
