## Health v2 (maintenance only)
Score: 67/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 8, longevity 100
- inputs: {"age_days": 2908, "days_push": 7, "days_rel": 560, "gap_med": null, "n_releases_24m": 1}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## Adoption (not part of the score)
Stars 36512, forks 9489 (observed 2026-08-28T04:12:01.145795+00:00)

## What it is
A community-maintained collection of LeetCode problem solutions implemented in many programming languages including Java, Python, C++, Go, TypeScript, and Rust. It also covers 'Coding Interviews' book problems and hosts a browsable wiki site at leetcode.doocs.org.

## Use cases
- prepare for coding interviews with worked algorithm solutions
- find LeetCode problem solutions in a specific programming language
- study data structures and algorithms with explanations
- practice 'Sword to Offer' and 'Cracking the Coding Interview' problems
- compare solutions to the same problem across multiple languages
- review past contest problems and solutions

## When to choose
- you are preparing for technical interviews or online coding assessments
- you want reference implementations of algorithm problems in several languages
- you prefer a free, community-driven alternative to paid interview prep sites

## When to avoid
- you need an interactive judge or auto-graded practice environment
- you want a structured course with progression tracking rather than a reference of solutions
- you need guaranteed correctness or editorial-quality explanations for every problem

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