Sparse arrays are a bit of a faff and only worthwhile in the specific
scenario where there are a lot of choices, so an if/elif ladder would be
cumbersome - I'm thinking at least double digit lengths...20 or 30 say.
They are also effective where you have a broad range of possible test
values but only a relatively few sub-ranges which require action.

It was purely a response to Bob's question about how to handle the
long ladder case. Not a general recommendation.
Certainly not for this particular problem.
