Final Remarks
The 2024-25 season seems to be flying by, with another successful contest behind us. I was glad to see strong performance and large numbers of promotions across the board, as well as smooth operation for the contest itself.
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 Chongtian Ma, Alex Liang, Haokai Ma, Andrew Li, Avnith Vijayram, Michelle Wei, Nick Wu, Nathan Wang, Brandon Wang, Spencer Compton, Tina Wang, Jichao Qian, Suhas Nagar, Ho Tin Fan, Daniel Zhang, William Lin, Larry Xing, Weiming Zhou, Benjamin Chen, Andi Qu, Thomas Liu, and Benjamin Qi. Thanks also to our translators for their help in extending the reach of our contests. Finally, we are exceedingly 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 contest, our national championship!
Happy coding!
