Maze generator & solver · hy3-preview

The user wants me to create a single-page web app that:
1. Generates a random maze using the recursive-backtracker algorithm
2. Renders it on a canvas
3. Animates an A* or BFS solver finding the path from start to finish

All code should be in a single index.html file with inline CSS and JS, no external resources.

Let me plan the implementation:

1. HTML structure with a canvas element
2. CSS for styling
3. JavaScript with:
   - Maze generation using recursive backtracker
   - Maze rendering on canvas
   - Pathfinding algorithm (I'll use BFS for simplicity, or A*)
   - Animation of the solver

Key components:
- Maze class with cells, walls
- Recursive backtracker algorithm
- BFS or A* pathfinding
- Animation loop

Let me write this out

The user asked me to generate a random maze with the recursive-backtracker algorithm on a canvas, then animate an A-star or BFS solver finding the path from start to finish. I've created a self-contained HTML file that does exactly this.

Let me verify the file was created correctly by reading it back or checking if it exists. The file should be at /workspace/index.html.

The implementation includes:
1. Recursive backtracker maze generation algorithm
2. BFS (Breadth-First Search) pathfinding algorithm
3. Canvas rendering for the maze
4. Animation of the solver exploring cells
5. Start (green) and end (red) points
6. Controls for generating new mazes and solving
7. Pause/resume functionality
8. No external resources - everything is inline

The user's request has been completed. I should confirm the file exists and maybe provide a brief summary of what was
