Floor Cleaner

You have built a floor cleaning robot and now you are writing an algorithm that will report all the locations of the house it could not clean. The robot has layout of the house that includes where the walls, furniture and flooring are. When it cleans it will log locations where it finds unexpected obstructions. Key:
