- description:
- Select optimal data structure based on operation requirements
Data Structure Selector Skill
Purpose
Select the optimal data structure based on required operations, their frequencies, and time/space constraints.
Capabilities
- Analyze required operations (insert, delete, query, update)
- Match to optimal data structure
- Consider time/space trade-offs
- Suggest augmentations for custom requirements
- Compare alternatives with complexity analysis
Target Processes
- data-structure-implementation
- algorithm-implementation
- complexity-optimization
Selection Framework
Operation Analysis
- What operations are needed?
- What are the frequency/priority of each operation?
- What are the constraints (N, Q, time limit)?
- Is persistence needed?
- Are range operations required?
Common Selection Patterns
| Operations | Best Choice | |------------|-------------| | Insert, Delete, Search | BST / Hash Map | | Range sum, Point update | Fenwick Tree | | Range query, Range update | Segment Tree + Lazy | | Union, Find | DSU | | Min/Max with add/remove | Multiset / Heap | | Predecessor/Successor | Ordered Set / BST |
