segment-tree-builder

Segment Tree Builder Skill

Purpose

Generate customized segment tree implementations for various merge functions, with support for lazy propagation and advanced variants.

Capabilities

• Generate segment tree for custom merge functions
• Lazy propagation template generation
• Persistent segment tree variants
• 2D segment tree generation
• Segment tree beats for complex updates
• Iterative vs recursive implementations

Target Processes

• segment-tree-implementation
• range-query-optimization
• data-structure-implementation

Segment Tree Variants

1. Basic: Point update, range query
2. Lazy Propagation: Range update, range query
3. Persistent: Version history preservation
4. 2D Segment Tree: 2D range queries
5. Segment Tree Beats: Complex range updates (chmin, chmax)
6. Merge Sort Tree: Range order statistics
