Write a program that performs the substraction of two matrices A and B of the same dimensions R and C.

Matrix B is subtracted from A.

\(\begin{pmatrix} a & b & c & d \\e & f & g & h \\ i & j & k & l \end{pmatrix} - \begin{pmatrix} a' & b' & c' & d' \\e' & f' & g' & h' \\ i' & j' & k' & l' \end{pmatrix} = \begin{pmatrix} a-a' & b-b' & c-c' & d-d' \\e-e' & f-f' & g-g' & h-h' \\ i-i' & j-j' & k-k' & l-l' \end{pmatrix}\)
