We will hold UOJ Long Round #3 contest!

The contest will run for 60 hours, spanning the entire weekend. You will be given 6 problems. (so it will be like a PA-Runda 5 contest XD)

Overall, the difficulty should be a bit easier than previous ULR contests (?). Everyone is welcome to come and enjoy solving them without worry.

Additionally, one of the problems will be judged with WASM-judge support. Special thanks to aberter0x3f. (Contestants may simply treat this as more precise time/space computation during judging, there is almost no perceptible difference during the contest. For technical details, see the post at https://yzy1.blog.uoj.ac/blog/9339.)

The contest will follow the IOI rules: Each problem can be submitted up to 128 times, and scores can be viewed in real-time. All the problems will have subtasks, the final score will be based on the highest-scoring submission.

You can see the scoreboard during the contest.

The contest is rated for everyone, but the rating change will only be 1/128 of a normal contest. So feel free to join just for fun!

We are looking forward to your participation!

UPD: Congratulation to the winners!
