Dear Zindians,
After an intensive code review session, the leaderboard is sealed.
Due to dataset changes during the competition, our review process was more thorough and comprehensive than usual. During code review we ensured that all the solutions did not have the "LastPayment" feature. If this feature was included, we dropped this feature, ran the code and updated the submission score on the leaderboard to that which we generated. If a requested solution was not submitted, we moved that user out of the top 10.
Thank you for your patience and trusting Zindi's process, and congratulations to the winners.
The Zindi Team
