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
