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

1. What operations are needed?
2. What are the frequency/priority of each operation?
3. What are the constraints (N, Q, time limit)?
4. Is persistence needed?
5. Are range operations required?

Common Selection Patterns

Input Schema

{
  "type": "object",
  "properties": {
    "operations": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "name": { "type": "string" },
          "frequency": { "type": "string" },
          "constraints": { "type": "string" }
        }
      }
    },
    "constraints": { "type": "object" },
    "preferences": { "type": "array" }
  },
  "required": ["operations"]
}

Output Schema

{
  "type": "object",
  "properties": {
    "success": { "type": "boolean" },
    "recommended": { "type": "string" },
    "complexities": { "type": "object" },
    "alternatives": { "type": "array" },
    "augmentations": { "type": "array" },
    "reasoning": { "type": "string" }
  },
  "required": ["success", "recommended"]
}
