Matrix exponentiation seq spoj

#1

after generarting transformation matrix successfully while returning the result for given n , why dont we multiply the last row which actually contains the coefficients (or did in starting) with given base matrix , and then return because fn also is in last (in left hand side ).

i was hoping to find someone who has gone through this problem and wont mind looking at my code and tell me where did i do wrong.

i was not suggesting i was just telling that i didn’t get some of that approach ,which i do consider as a doubt. And that has been solved anyway.
