The Algorithms - GitHub's largest open-source algorithm library
It's not a single repo, but an entire collection: algorithms and data structures implemented in virtually every language — Python, Java, C, C++, JavaScript, Rust, Go, Julia, Fortran, Zig, Nim, and even Mojo.
Every repository is educational by design: sorting, searching, graphs, dynamic programming, mathematics, machine learning, physics. Clean, readable code under open licenses.
The scale speaks for itself: the Python repo alone has 222k stars, Java has 66k — making these some of the most popular educational projects on GitHub, period.
Who it's for:
• Learning algorithms — see the implementation in your language of choice
• Prepping for interviews — the perfect reference
• Want to break into open source — plenty of issues tagged "help wanted"
Free, open, community-maintained.
