Not that I particularly care, but I wonder why I got a down vote for having written my above post. I just can't really make sense of the input data and of the expected result in the way these are currently formatted. But perhaps the problem has to do more with the person who downvoted my post than with the content of my post.

I suspect you are correct in your last statement.

Best guess I would have is that someone perhaps thought it looked like an advanced "me too" post and they have a bug up their behind about those or something.

It's a reach, I admit, but the only thing I could think of.

Otherwise, probably just someone being a bit of a snot.

I got downvoted earlier today for admitting I didn't know something.  LOL. Who knows what goes through peoples' minds?

Dear marinersk, it appears that you also got downvoted just for having answered to my post! I can figure that out because, after I upvoted your post above, its reputation got to 0, meaning that it was -1 beforehand. These are things that I don't understand...

Just like downvoting a monk who admits not knowing something is ridiculous in my view. I have read carefully the voting guidelines published on this forum, and came to the policy that I would not downvote a post making a big mistake in a coding effort to help out another monk (everyone can make a mistake) or even a post making a claim that happens to be plain wrong. I have been downvoting posts only extremely rarely (perhaps a dozen times so far, twenty at the very most), when someone is stubbornly maintaining something wrong despite having be proven the opposite, or when someone is being blatantly nasty or obnoxious with other monks. I even voluntarily avoided to downvote posts in which I felt that people were being somewhat mean against me personally (fortunately, this has happened only a couple of times), because I thought that this would be improper for me to do so (but I am not saying that I would never do it, I might possibly do it if someone became really nasty against me).

Having said all that, independently of its high technical quality, this is also a very nice forum and, by far, most monks are very nice persons with whom I would be delighted to have a beer or a meal in the evening. I love to be here and easily forget about the very few hitches here and there.

Well, sorry to all if this is an off-topic comment.
