## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 2802, "days_push": 8, "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)

## What it is
A free, open-source study guide and web app that groups 179 LeetCode questions by recurring problem-solving patterns to prepare for software engineering coding interviews. It includes a pattern-based question list, heuristic tips for choosing approaches, and Java solutions.

## Use cases
- prepare for coding interviews with a pattern-based study plan
- find which algorithm pattern applies to a given problem constraint
- practice a curated list of leetcode questions grouped by topic
- review data structure fundamentals and runtimes before interviews
- look up Java solutions for common interview questions

## When to choose
- you want a free, curated, pattern-first roadmap for leetcode-style interview prep
- you learn best by repeatedly applying common techniques rather than random problems
- you want a quick reference mapping problem constraints to candidate approaches

## When to avoid
- you need a full interactive coding judge or IDE - use leetcode.com itself
- you want system design or behavioral interview preparation
- you need solutions in languages other than Java
