Codeforces Round #691 Editorial (currently updating)

Revision en3, by Endagorion, 2020-12-19 22:00:41

Keeping track of both Codeforces round and online team contest was a doozy, so this is only the best draft of the editorial I have. Missing problems will gradually be added, and existing explanations may improve over time. Hope you enjoyed the problems, and let me know if anything can be explained better!
