Answer 1

N and M are the values needed to make the map. Really you only need N to find out M because M is 3x N. Since N is always an odd number the Mat will always have a middle. Build the pattern where •|• appear in the middle of the -----•|•----- then add 2 •|• to the middle and remove enough --- to get ---•|••|••|•--- until you reach the vertical middle which would be (N - 1) / 2. If you want the middle of M it will be the same thing as N except you want to compensate for •|•. If you want more help I will solve the problem later and send you the solution to read through
