Charlie's answers are nearly always correct.

Novices often think that "No Solution Yet" means something when in fact it means very little.  What it officially means is that no official solution has been put up by the powers that be.  Many problems go for eons without any official solution.  Often one of the comments gives what is obviously a correct solution, but no official solution yet exists. And sometimes the official solution is less than correct. To see what an official solution looks like, go to Home, scroll clear down to the bottom of the page, and click on one of the ones listed there. See also FAQ.
