Yesterday I asked this question which was very quickly put on hold.
As I rarely contribute here, I wouldn't have been surprised if my question has been closed as uninteresting, or too hard, or too easy, but the last thing I expected was the reason currently alleged, "unclear what you're asking". How anybody could find that full problem statement unclear is beyond me.
An upvoted comment indicates that my question makes perfect sense to several other users. My last comment asking for my critics to clarify what they found unclear got no answer at all.
