Final Remarks
I'm happy to see sustained high levels of participation throughout the 2022-2023 season so far. The February contest was quite challenging, particularly in the silver division, yet we are still seeing healthy numbers of promotions.
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 Brandon Wang, Claire Zhang, Benjamin Qi, Danny Mittal, Mark Gordon, Rohin Garg, Jesse Choe, Nathan Wang, David Hu, Mihir Singhal, Andi Qu, Spencer Compton, and Richard Qi. 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: Citadel, Ansatz, X-Camp, TwoSigma, VPlanet Coding, EasyFunCoding, Orijtech, and Jump Trading.
We look forward to seeing everyone again for the US Open, our final contest of the season!
Happy coding!
