[b]Edit: The contest is over! Many thanks to all of you who participated. The questions have been cloned to the main judge. We will be posting prizewinners and analyses to all of the problems shortly. Check here, as well as our website periodically! Feel free to submit to them for practice while we work on publishing results and analyses. Note that questions are shared between divisions. In particular, submissions to all intermediate problems are not moved over and intermediate competitors will have to resubmit them on the main judge.[/b]
