One of the things I can't stand while doing cp is encountering problems with circular arrays whose solution is almost identical to the analogous problem with a "normal" array. Circular arrays usually make problems more tedious to write.
I'm not blaming about problems like 1334C - Circle of Monsters, that have a "natural" solution with a circular array and turn out to have a quite different solution if the array is linear.
I'm blaming about problems like 1392D - Omkar and Bed Wars and 1328D - Carousel. Let's suppose that the array is linear, the solution is identical! The circular array only adds a bunch of cases.
