## Health v2 (maintenance only)
Score: 76/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 98, release rhythm 35, longevity 100
- inputs: {"age_days": 4143, "days_push": 17, "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 classic algorithms and data structures implemented in many programming languages including C, C++, Java, Python, Go, Ruby, JavaScript, Swift, Rust, Scala, and Kotlin. It also includes extra problems commonly encountered in programming challenges and interviews.

## Use cases
- learn sorting algorithms with implementations in multiple languages
- study data structures for coding interviews
- compare algorithm implementations across languages
- practice classic computer science problems
- find reference implementations of searching algorithms
- contribute to an open-source educational algorithms repository

## When to choose
- you want to learn or review algorithms and data structures with real code examples
- you need to see the same algorithm implemented in different programming languages
- you are preparing for technical interviews or programming challenges
- you want a beginner-friendly open-source project to contribute to

## When to avoid
- you need a production-ready, optimized algorithm library for an application
- you need a maintained package with APIs, tests, and versioned releases
- you need specialized or advanced algorithms not covered by classic CS topics

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools
- domain: education, programming-languages, tutorials
- platform: cross-platform
- tags: data-structures, sorting-algorithms, searching-algorithms, interview-prep, competitive-programming, multi-language, hacktoberfest, algorithms
