No, I never did really. Programming an elevator sounds very tedious, but it never sounded very hard. Elevators are heavy equipment, and there are edge cases around safety near heavy equipment: I&#x27;d rather not have to learn those first-hand.<p>However, I do think this is a great exercise for people new to programming. It&#x27;s a common enough scenario that most people can recite 80% of the requirements of an elevator from memory.
