## Overview

This repository is a Chinese-language algorithm-learning library: its main workflow is for a learner to use the README’s study guidance and article index to find explanations, study reusable algorithm and data-structure ideas, and apply them to interview-style problems. Its runtime is curated Markdown, not an application. The README also describes a companion site, visualization, games, and editor/browser plugins; these are documented ecosystem capabilities, not implementations present in this tree, so their wiring is not inferred.

Main entry points: [`README.md`](https://github.com/labuladong/fucking-algorithm/blob/master/README.md) (Article index), [`技术/刷题技巧.md`](https://github.com/labuladong/fucking-algorithm/blob/master/%E6%8A%80%E6%9C%AF/%E5%88%B7%E9%A2%98%E6%8A%80%E5%B7%A7.md) (Study guidance), [`动态规划系列/README.md`](https://github.com/labuladong/fucking-algorithm/blob/master/%E5%8A%A8%E6%80%81%E8%A7%84%E5%88%92%E7%B3%BB%E5%88%97/README.md) (Dynamic programming), [`数据结构系列/README.md`](https://github.com/labuladong/fucking-algorithm/blob/master/%E6%95%B0%E6%8D%AE%E7%BB%93%E6%9E%84%E7%B3%BB%E5%88%97/README.md) (Data structures)
