What is this?
Hello Algorithm (小浩算法) is a free, Chinese-language collection for beginners learning algorithms, bundling illustrated LeetCode solutions, big-tech interview write-ups, open-source ebooks, and mind maps.
Is this a coding library or a study guide?
It's a curated study resource, not a code library: markdown notes, PDFs, and mind maps organized into four parts covering algorithm basics, LeetCode walkthroughs, interview experiences, and CS knowledge summaries.
Is this still being actively updated?
Parts 1 and 2 are complete, but Part 3 (interview write-ups) is explicitly marked as still being updated and Part 4 (CS knowledge summary) is listed as TODO, so coverage is uneven across parts.
Is there an English version?
Yes — the README mentions an English translation repo and a Gitbook version maintained on a separate English branch.
Can I download the LeetCode guide as a PDF?
Yes, the project offers a complete PDF download of its illustrated LeetCode solutions guide ('小浩图解算法题典.PDF').
How many interview write-ups are included?
Around 50 curated big-tech interview experience articles, selected and categorized by the author to avoid the duplication common in other 'BAT interview' lists online.
