## 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": 3217, "days_push": 2162, "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 Chinese-language learning resource on data structures and algorithms, packaged as an Android application with Java code examples. It covers time/space complexity, sorting, linked lists, binary trees, red-black trees, graphs, and Java/Android interview questions.

## Use cases
- learn data structures and algorithms with Java examples
- prepare for Java and Android interview questions
- understand time and space complexity of algorithms
- study sorting algorithms like quicksort and bubble sort
- learn graph algorithms like Dijkstra and topological sort
- review binary tree, red-black tree, and AVL tree concepts

## When to choose
- you are a Java or Android developer preparing for technical interviews
- you want runnable code examples of classic data structures and algorithms
- you prefer learning algorithm concepts in Chinese

## When to avoid
- you need a production data structure library to use in your own code
- you want actively maintained content or English-language tutorials
- you need a non-Java implementation of these algorithms

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools
- domain: education, tutorials
- platform: jvm, cross-platform
- tags: data-structures, algorithms, interview-preparation, java, android-app, time-complexity, sorting, graphs, binary-trees, chinese, android
