I would consider this more of a solution to a programming problem than something which is algorithmically very involved so I'm afraid I'm not sure this is in scope. @raklaptudirm what do you think?

@appgurueu This solution is an approach to solving similar spiral matrix-related problems. Does that make sense? If not, could you please suggest any changes?

This solution is an approach to solving similar spiral matrix-related problems.

I'm aware of what this code implements. I'm just not convinced it fits here: I think it's more of a "programming" problem than an "algorithm" problem, if that makes sense.
