The rest of this answer is completely useless, so feel free to skip it. The reason I'm posting additional words is because otherwise the answer [would be considered "trivial" and converted to a comment][1], and it looks like adding a bunch of text is the only way to be sure (other than [nuking it from orbit][2], of course).
