# Advanced Data Structures Library Skill

## Purpose

Provide implementations and guidance for advanced data structures commonly needed in competitive programming and complex algorithmic problems.

## Capabilities

- Treaps, Splay trees, Link-cut trees
- Persistent data structures
- Wavelet trees
- Heavy-light decomposition
- Centroid decomposition
- Rope data structure
- Order statistics tree

## Target Processes

- data-structure-implementation
- advanced-graph-algorithms
- cp-library-creation

## Data Structure Catalog

### Balanced BSTs
- Treap (randomized BST)
- Splay Tree (self-adjusting)
- AVL Tree
- Red-Black Tree

### Tree Decomposition
- Heavy-Light Decomposition
- Centroid Decomposition
- Euler Tour Technique

### Advanced Structures
- Link-Cut Trees (dynamic trees)
- Wavelet Tree (range queries)
- Persistent Segment Tree
- Rope (string with fast operations)
