USACO 2021 February Contest, Platinum
The platinum division had 413 total participants, of whom 290 were pre-college students. Like the other contests this season, the platinum contest proved to be quite challenging, with only a small number of very high scores. Results for top scorers are here. Congratulations to all of the top participants for their excellent results!

Final Remarks
Happy to see another contest running relatively smoothly, with a good contingent of promotions. The 2020-2021 season is now nearly finished, with just one more contest to go!
For those not yet promoted, remember that the more practice you get, the better your algorithmic coding skills will become -- please keep at it! USACO contests are designed to challenge even the very best students, and it can take a good deal of hard work to excel at them. To help you fix any bugs in your code, you can now re-submit your solutions and get feedback from the judging server using "analysis mode".
A large number of people contribute towards the quality and success of USACO contests. Those who helped with this contest include Benjamin Qi, Dhruv Rohatgi, Spencer Compton, Andi Qu, David Yang, and Danny Mittal. Thanks also to our translators and to Clemson CCIT for providing our contest infrastructure. Finally, we are grateful to the USACO sponsors for their generous support: Ansatz, X-Camp, TwoSigma, and Jump Trading. I'm particularly happy to welcome Citadel to the USACO family as a prime sponsor --- many thanks for helping to support our initiatives and high-school computing in general!
We look forward to seeing everyone again for the 2021 US Open contest, our final contest of the season.
Happy coding!
