Avoiding the case block

[jerryjohnjacob]

As a brainstorming exercise, can you try figuring out if there's any way you can avoid using the case block here?

Usually the switch-case block is regarded as unclean code. I don't quite agree with that. What I do think is that the tendency is generally to misuse it and hence it ends up getting used in inappropriate places. I think your current use of it is fine. But like I mentioned, as an exercise, just think about other means through which you can implement the same (no need to update the code or anything).
