Final Remarks
Just one more contest to go in the season! Results in the February contest look reasonably comparable to those in past contests, with promotion cutoffs being set a bit lower in some divisions due to their challenging problem lineups. Overall, this contest ran quite smoothly.
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, Danny Mittal, Andi Qu, Jesse Choe, Nick Wu, Daniel Zhang, Richard Qi, Timothy Qian, and Alex Liang. 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, EasyFunCoding, and Jump Trading.
We look forward to seeing everyone again for the 2022 US Open, our national championship contest.
Happy coding!
