What is it?

leetcode-master is a structured algorithm study plan written in Chinese, known as 《代码随想录》. It arranges about 200 classic LeetCode problems in a recommended order grouped by topic, from arrays and linked lists through trees, backtracking, greedy, dynamic programming and graphs.

Each topic includes theory notes, the problems themselves, and a summary chapter. Solutions are illustrated with diagrams and mind maps, with video walkthroughs for harder problems. The main explanations use C++, and community-contributed implementations are provided in Java, Python, Go and JavaScript.

The repository is mainly Chinese-language content, with an English edition hosted separately and a Gitee mirror for readers in mainland China.
