Write a program that performs the transposition tA of a matrix A of dimensions N and M into a matrix of dimensions M and N.
The matrix A will be transposed by permutation of the elements
\(^{t}A = ^{t}\begin{pmatrix} a & b & c & d \\e & f & g & h \\ i & j & k & l \end{pmatrix}= \begin{pmatrix} a & e & i \\ b & f & j \\ c & g & k \\ d & h & l\end{pmatrix}\)
