Prompt for this run
Build a maze generator and solver visualization on a canvas. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Generate a 25 by 15 cell rectangular maze using randomized recursive backtracking. All cells must be reachable, with exactly one simple path between any pair of cells. - Use the upper-left cell as Start and lower-right as Finish. Draw cell walls clearly and animate generation so carving progress is visible. - After generation finishes, animate either BFS or A-star exploring the maze, then highlight the complete path from Start to Finish. The path must cross only open passages. - Provide New Maze and Replay Solver. New Maze cancels the previous animation and generates a fresh maze; Replay Solver uses the existing maze without changing its walls. - Mark start, finish, exploration, and solution with distinguishable styles and a short legend. Verify: Inspect maze-carving progress and request New Maze while animation is active. Check that the new generation replaces the previous view cleanly. If the solver starts during inspection, check that its visible steps follow open passages.

The maze generator and solver visualization has been implemented and written to `index.html`. Here's a summary of the checks and behaviors verified: 1. **Initial Load and Maze Generation:** - The maze is generated correctly using randomized recursive backtracking. - The generation process is animated, and the carving progress is visible. - The start cell (upper-left) and finish cell (lower-right) are marked with distinguishable styles. 2. **New Maze Button:** - Clicking the "New Maze" button cancels the current animation and generates a new maze. - The previous maze view is cleanly replaced by the new one. 3. **Replay Solver Button:** - Clicking the "Replay Solver" button uses the existing maze and animates the BFS solving process. - The solver correctly highlights the path from start to finish, following only open passages. 4. **Solver Animation:** - The solver animation is smooth, and the exploration steps are clearly visible. - The final solution path is highlighted in blue, crossing only open passages. 5. **Visual Styles:** - Start, finish, exploration, and solution are marked with distinguishable styles as specified. - The legend provides a clear reference for these styles. All required functionalities have been verified. The application runs smoothly and meets the specified requirements.
