// the take
A personal collection of Java solutions to roughly 60 LeetCode problems, split into easy/medium/hard tiers with a written explanation per problem in a note/ directory. It's aimed at developers prepping for interviews, particularly ones targeting Facebook since it includes a curated list of FB-tagged problem numbers.
Each solution is paired with a markdown writeup in note/NNNN/README.md rather than just bare code, which is more useful for actually learning the approach than a code-only dump. The Facebook interview question list (with direct LeetCode numbers) is a genuinely specific, useful artifact if you're prepping for that particular interview loop. Solutions are organized by difficulty and problem number, making them easy to look up.
Dead since December 2020 with no commits in 5 years, despite the README calling itself 'updating' - the problem set stalled at roughly 60 solved out of 150+ originally referenced, so most interview-relevant problems (dynamic programming, graphs, backtracking beyond the basics) are simply missing. No tests of any kind, so there's no way to verify a given Solution.java is actually correct beyond reading it. The README and several note files are written in Chinese, which limits usefulness if you don't read it, and there are many other LeetCode-in-Java repos with far broader coverage and active maintenance to choose from instead.
We read the README, the directory tree and a key source file in October 2026. Nobody pays to be listed. How we judge →
