enhance pattern detection to support more patterns(#44)

[yours-truly-anshika]

I have successfully extended the Pattern Recognition feature in CodeClarity to detect a comprehensive set of data structures and algorithms. Here's what was accomplished:

---

Patterns Added (10 new patterns)

Data Structures:

• Queue (FIFO operations)
• Stack (LIFO operations)
• Binary Tree (hierarchical structure)
• Graph (vertices and edges)

Sorting Algorithms:

• Quick Sort (divide-and-conquer)
• Merge Sort (stable sorting)
• Heap Sort (heap-based sorting)

Graph Traversal:

• Depth-First Search (DFS)
• Breadth-First Search (BFS)
• Binary Search Tree Operations

Technical Improvements

• Enhanced Pattern Detection Logic - Added specific confidence calculation for each new pattern with keyword matching and structural analysis
• Extended ML Engine - Updated pattern signatures, structural pattern detection, and complexity indicators for all new algorithms
• Rich Visualizations - Created comprehensive visualizations including:
  • Tree structures for binary trees and BST
  • Network diagrams for graphs
  • Flowcharts for sorting algorithms
  • Sequence diagrams for queues and stacks
• Educational Content - Added both simplified and technical explanations for each pattern, making the tool more educational

Benefits Achieved

• 3x Pattern Coverage: Extended from 5 to 15+ detectable patterns
• Better Educational Value: Comprehensive explanations and visualizations
• Consistency: All new patterns follow the same interface and detection patterns
• Accuracy: Enhanced confidence scoring ensures reliable pattern detection
• Maintainability: Well-structured code that's easy to extend further

How It Works Now:

1. Load Examples: Go to Tools tab → Load Example → Select any new pattern
2. Real-time Detection: Switch to Pattern Recognition tab to see live analysis
3. Multiple Patterns: The system now detects 15+ patterns instead of just 5

User Experience:

• Real-time Analysis: No more static examples - analyzes your actual code
• Confidence Scoring: Shows how confident the system is in each detection
• Educational Value: Rich explanations and visualizations for learning
• Multiple Patterns: Can detect multiple patterns in the same code
• Interactive: Click on patterns to see detailed explanations and visualizations

The Pattern Recognition feature now provides comprehensive coverage of fundamental computer science concepts, making CodeClarity a powerful educational tool for learning algorithms and data structures while maintaining consistency with existing features.
