Introduction

This section describes the background of this problem. This part is not directly related to the problem.

The Cherry Contest that Kazun hosts on yukicoder is being held for the 5th time this time (the 6th time if the Mathematics era is included).

In the Cherry Contest, each problem name is prefixed with something like [Cherry 1st Tune A]: after "Cherry" comes the numbering that denotes the contest, followed by a character determined by a certain rule (not explained here) ((なし), *, A, B, C, D, N) (the same character may be attached to different problems). In a sense, this serves as a problem code.
