My first attempt at really playing code golf, that is solving a problem in minimum characters of code and I did not do very well (200 character compared to the best 43 perl or 63 ruby characters).
m = 
r = 
c = Array.new(10, 0)
I further squeezed some white-space out of the code and it is starting to look uglier (now it is 184 characters). I am not sure I like the code golf concept although I like to solve coding problems.
