In MATLAB, there is a very useful function called 'reshape', which can reshape a matrix into a new one with different size but keep its original data.

A matrix is Toeplitz if every diagonal from top-left to bottom-right has the same element.

On a 2 dimensional grid with R rows and C columns, we start at (r0, c0) facing east.

The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix.

A move consists of choosing any row or column, and toggling each value in that row or column: changing all 0s to 1s, and all 1s to 0s.

We are given an array A of N lowercase letter strings, all of the same length.
