## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 4341, "days_push": 1049, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated collection of LeetCode problem solutions written in C++11 and Python3, organized by problem with accompanying notes. It serves as a study reference for algorithms and data structures practice.

## Use cases
- prepare for coding interviews with worked leetcode solutions
- study algorithm problems in C++ and Python
- find reference implementations for classic data structure problems
- review notes explaining leetcode problem approaches
- practice solving algorithm questions with example answers

## When to choose
- you want readable C++11 or Python3 solutions with explanatory notes
- you are preparing for technical interviews and want problem-by-problem references
- you prefer solutions organized by difficulty and topic tags

## When to avoid
- you need a runnable judge or testing harness rather than reference solutions
- you want solutions in other languages or for platforms other than LeetCode
- you need actively updated coverage of the newest LeetCode problems

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools
- domain: education, programming-languages
- platform: cpp, python
- tags: leetcode, interview-preparation, coding-interview, data-structures, algorithms, solutions, competitive-programming
