# Chaos-vy/ChaosTree

> A zero-dependency Java Sorted Set/Map library built on AVL, Red-Black, B-Tree and B+Tree structures, exposing JDK-style NavigableSet/NavigableMap and SequencedCollection APIs. Validated by Guava Testlib and property-based tests, with JMH benchmarks.

## Useful for

- Swap java.util.TreeMap for BPlusTreeMap to speed up large range queries via subMap
- Bulk-load sorted data in O(N) with buildFromSorted when constructing a B-Tree
- Run the JMH benchmarks to compare AVL, RBT, BTree and BPlusTree under your own workload

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
