Use the correspondence scheme above to convert the following to numeric values, in the
form of a 3x8 matrix (8 columns of 3x1 vectors). Remember, the encryption/decryption
process is down the first column, then to the next column, so the first column should be the
equivalent of MAR in the plaintext below. If necessary, use space(s) at the end to fill in your
matrix. Don't forget the spaces and period! Name your plaintext matrix B.
