What did you want to know about or do with this little number? I find it rather presumptuous on your part to simply assume that you can toss a number out as a problem submission and that someone will simply magically know what you want. I also think it indicates that you are simply too lazy to actually type out the question you want to ask. If you are going to be that lazy, why should we do any work at all for you? By the way, I'm deleting your other similar submissions.
