It seems that someone gives us a problem to solve, tags the question code-golf and the winner is whoever completes the solution in the fewest characters. I haven't found a reference for what it is, so lets discuss its purpose here.
EDIT: OK, we've explained what it is, but why stage a competition to see who can use the least number of characters? It's an interesting contest (and that may be the point and I'm looking too deeply) but it doesn't seem to have any other reason. It is terrible to read; I think we could have more interesting contests to see who could make the fastest or most flexible or otherwise "best" solution.
