[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 J3 and S1 are the same question, as are J4 and S2. Thus, submissions to J3/J4 are not moved over and junior competitors will have to resubmit them to S1/S2 on the main judge.[/b]
