## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 2652, "days_push": 612, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## Adoption (not part of the score)
Stars 6189, forks 732 (observed 2026-08-28T04:09:38.941256+00:00)

## What it is
A curated collection of solutions and explanations for all LeetCode coding problems, written primarily in Chinese with accompanying video explanations. It serves as a comprehensive study reference for algorithm and data structure interview preparation.

## Use cases
- prepare for coding interviews with leetcode problems
- learn algorithms and data structures with worked examples
- find explanations for hard leetcode problems in Chinese
- study solutions before a technical interview
- practice data structure and algorithm questions
- look up how to solve a specific leetcode problem

## When to choose
- you want comprehensive coverage of nearly all LeetCode problems with explanations
- you prefer explanations written in Chinese
- you want a single indexed reference linking each problem to a detailed solution

## When to avoid
- you need an executable tool or automated judge rather than written solutions
- you want explanations in English only
- you need a maintained library with a license for commercial reuse

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools
- domain: education, tutorials, programming-languages
- platform: cross-platform
- tags: leetcode, interview-preparation, coding-interview, data-structures, algorithms, chinese-language, solutions, competitive-programming
