## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 2586, "days_push": 7, "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 Baekjoon Online Judge problem sets organized by algorithm topic for coding test preparation. It includes recommended problems per algorithm category, study links, and analyses of algorithms appearing in recent company coding tests.

## Use cases
- prepare for coding tests with curated problem lists
- practice algorithms by topic on Baekjoon
- find recommended problems for interview prep
- study which algorithm types appear in company coding tests
- find beginner-friendly algorithm study resources
- track progress through algorithm problem sets

## When to choose
- you are preparing for technical interviews or coding tests using Baekjoon
- you want topic-organized problem lists with recommended picks
- you want to know which algorithms companies test recently

## When to avoid
- you need algorithm concept explanations rather than problem lists
- you want solutions in languages other than C++ (Python/Java planned but not yet complete)
- you need an interactive practice platform (this is a problem collection, not a judge)

## Facets
- artifact type: learning-resource
- maturity: active
- function: math
- domain: education, developer-tools
- platform: cross-platform
- tags: coding-test, baekjoon, competitive-programming, problem-sets, interview-preparation, korean, education, problem-solving, algorithms
