Sure. Did I miss some hint that this program might need to be more
flexible like that? It looks like a beginners' exercise.
If the purpose is to be flexible, why is an array the right option rather
than, say, accumulating a value over an iterable? You need some idea of
the future direction or what the exercise is intended to reinforce.
