🧩 Additional Tools

🗺️ Map Generator (`my_map_gen.c`)

Note: This file is included but not currently integrated into the main build.

Features:

Algorithmic Map Generation: Uses recursive pathfinding (similar to Mr. C algorithm)
Validation System: Ensures generated maps have valid solutions
Customizable Parameters: Configurable obstacles and collectibles
Path Verification: Flood-fill algorithm to verify map solvability

Usage Concept:

# Theoretical usage (if integrated):
./map_generator <width> <height> <collectibles> <obstacles>
# Generates: Random map with guaranteed valid path from start to finish

Algorithm Overview:

Grid Generation: Creates bordered map with walls
Random Placement: Adds obstacles and collectibles randomly
Path Validation: Uses recursive flood-fill to verify connectivity
Solution Guarantee: Ensures all collectibles are reachable from start to exit
