One member of each of these five teams will receive a travel award to attend the SIGMOD conference in Houston, where we will announce the runner up and overall winner of the contest.


The leaderboard ranks the best submission of each team based on their performance in all tests. Only submissions that pass all available tests are considered for the leaderboard. Progress bars indicate how each submission fares in comparison with the other submissions on the leaderboard: the longest total runtime has an empty progress bar, while the fastest submission receives a full bar. The test sizes refer to the size of the input.
