UTPC Spring 2024 Open Contest Editorial Hope you enjoyed our contest! The editorial is below: [A &mdash; Skipping Songs](https://mirror.codeforces.com/gym/105109/problem/A) Author: [user:sg2themax,2024-04-21] <spoiler summary="Solution"> For this problem, you maintain an index counter pointing to the current song, starting at 0. At each step, you always ensure that you mod by the length of the record. You start off by playing the song at the index of the first number. After printing each song, you increment by one since Noah has "finished listening" to it. Then, you add the number of skips, print the next song, and repeat. </spoiler> [B &mdash; 6th heaven](https://mirror.codeforces.com/gym/105109/problem/B) Author: [user:blueberryJam,2024-04-21] <spoiler summary="Solution"> We first check whether the conditions can be satisfied, then if so compute the number of arrangements. #### Pruning Consider a situation in which a disk appears three times or more among all the distinct pairs.

UTPC Fall 2024 Contest #1 Editorial Hope you enjoyed our contest! The editorial is below: [A &mdash; Spookeepy](https://mirror.codeforces.com/gym/105346/problem/A) Author: [user:porkchops,2024-09-19] <spoiler summary="Solution"> We can use distance formula to calculate the distance from each point in the map to your current location. We return the point with minimum distance. If there are multiple points at the same minimum distance, keep the point with the smallest x-coordinate, and if there is still a tie, keep the point with the smallest y-coordinate (as stated in the problem description). </spoiler> [B &mdash; Ternary Nightmare](https://mirror.codeforces.com/gym/105346/problem/B) Author: [user:B-1168,2024-09-19] <spoiler summary="Solution"> The specific mixtures of 0, 1, and 2s are not as significant as the length of contiguous blocks of 0s and 1s (those "contiguous blocks" can have length 0, when between consecutive instances of 2). For example, we can parse the $1201012200120012$ sample into 0-1 blocks of le...

UTPC Contest 10-01-21 Editorial? Is there an editorial published somewhere? I have checked [UTPC's official website](https://www.cs.utexas.edu/users/utpc/index.html) but couldn't find anything. Would love to see some explanations for the harder problems. Participants' solutions can't be viewed, is this intentional too?
