## What it is
A Chinese-language tutorial collection teaching algorithms and data structures, with Java implementations and curated LeetCode practice problem sets organized by topic. It covers complexity analysis, sorting, recursion, divide-and-conquer, greedy, BFS/DFS, backtracking, dynamic programming, and core data structures like stacks, trees, heaps, graphs, and segment trees.

## Use cases
- learn algorithms and data structures systematically
- prepare for coding interviews at big tech companies
- practice LeetCode problems by category
- study for ACM/ICPC competitive programming
- review dynamic programming and graph algorithms before an interview
- find a structured刷题 (problem-solving) study plan

## When to choose
- you want a free, structured Chinese-language algorithm curriculum
- you are preparing for technical interviews and need topic-organized LeetCode practice
- you prefer Java example implementations
- you are an ACM/ICPC competitor reviewing fundamentals

## When to avoid
- you need English-language tutorials
- you want complete coverage of all data structures (some sections are unfinished)
- you need an actively updated resource (last release was January 2022)
- you want interactive exercises rather than markdown tutorials

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools
- domain: education, tutorials
- platform: cross-platform
- tags: data-structures, interview-preparation, competitive-programming, leetcode, java, acm-icpc, chinese-language, algorithms
