## What it is
A Java code library of data structures and algorithms for competitive programming, including segment trees, graph algorithms, string algorithms, math, and geometry. It also includes practice curricula and problem categorization sheets for training.

## Use cases
- prepare for competitive programming contests
- find ready-to-use implementations of segment trees and Fenwick trees
- reference graph algorithms like max flow and shortest paths
- study string algorithms such as suffix arrays and KMP
- follow a structured curriculum to learn algorithms by level
- reuse tested algorithm templates during contests

## When to choose
- you compete in programming contests using Java and want battle-tested templates
- you want a curated collection of classic data structures and graph algorithms
- you need a learning curriculum with categorized practice problems

## When to avoid
- you need a production-grade library with package management and semantic versioning
- you work in a language other than Java
- you need general-purpose application development utilities rather than algorithm templates

## Facets
- artifact type: library
- maturity: maintenance
- function: developer-tools
- domain: education, programming-languages
- platform: jvm
- tags: competitive-programming, data-structures, graph-algorithms, java, algorithms, interview-preparation
