I can never remember whether this kind of thing requires permutations or combinations; and the quickest way for me to be sure is to write the three lines of code it takes to check.

Once those three lines are written, don't you think it would be bloody mean to withhold them, just so that those who's only contribution to PM is to post "This isn't a code writing service.", are proved correct?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)
In the absence of evidence, opinion is indistinguishable from prejudice.
