You
are given a n*m size matrix A. The matrix has n rows and m columns. The element
at the i-th row and j-th column is A_{i,j}. Consider two sub-matrices in it, these two sub-matrices are defined by (i) the coordinates
of the top left elements of these two sub-matrices are (x1, y1) and (x2, y2),
respectively, and (ii) the size of each sub-matrix is l1*l2. The matrix
swapping operation is swapping every elements pair
in these two sub-matrices.
For example, for all i (0 ≤ i < l1) and j (0 ≤ j < l2), swap A_{x1+i,y1+j }and A_{x2+i,y2+j}.

**We guarantee these two swapping sub-matrices
are not adjacent or overlapping**.

What the result matrix is after applied q times matrix swapping operations?
