Description

Implemented QuickSort Visualizer with interactive step-by-step animation showing the divide-and-conquer sorting algorithm.

Features Added:

• ✅ Visual representation of QuickSort algorithm with array bars
• ✅ Color-coded visualization:
  • 🟡 Yellow: Pivot element
  • 🔵 Blue: Elements being compared
  • 🟢 Green: Elements in correct position
  • ⚪ White: Unsorted elements
• ✅ Interactive controls:
  • Adjustable array size (5-100 elements)
  • Variable animation speed (10ms - 1000ms)
  • Generate new random array
  • Start/Reset functionality
• ✅ Real-time statistics display:
  • Current algorithm state
• ✅ Responsive design with Tailwind CSS
• ✅ Step-by-step explanation panel showing partition process

Implementation Details:

• Created QuickSort.jsx page component
• Implemented quickSortAlgorithm.js with generator function for visualization steps
• Added visual feedback for pivot selection and partitioning
• Optimized rendering performance for smooth animations

Checklist

• I have read the Contributing Guidelines
• My code follows the project's coding style
• I have tested the visualizer with different array sizes and speeds
• The component is responsive and works on different screen sizes
• All controls (speed, array size, generate, start, reset) work as expected
• Color coding accurately represents algorithm states
• Statistics (comparisons, swaps) are accurately tracked and displayed

Note: This implementation follows the same pattern as existing algorithm visualizers in the project for consistency.
