Using the correspondence (1), we encoded the following message by a $2 \times 2$ matrix: $\left(\begin{array}{rrrrrrrrrrr}17 & 16 & 18 & 5 & 34 & 0 & 34 & 20 & 9 & 5 & 25 \\ -30 & -31 & -32 & -10 & -59 & 0 & -54 & -35 & -13 & -6 & -50\end{array}\right)$ Decode the message if its first two letters are DA and its last two letters are AY.
