Edit 2: All solutions have been judged, and final results will be announced over the next few days. Problems and submissions have been copied to the main judge. Note that questions are shared between divisions. In particular, submissions to all intermediate problems are not moved over and intermediate contestants will have to resubmit to get points on the main judge.

Problems: J1, J2, J3/I1, J4/I2, I3/S1, I4/S2, S3, S4

Edit: The contest is over! We realize that the submission queue for this round was heavily backlogged and apologize for the inconvenience. Submissions will remain to be judged for the next while, and results will not be finalized until the end of the night. After that, we will move the problems to the main judge. While you wait, please feel free to check out the solutions and test data, which have been posted here: Thank you for your understanding.
