If we use the Hill cipher with $m=3,26$ English letters and $10$ decimal digits to encrypt plaintext "Engineer$2"$ by using the key matrix

$\left[\begin{array}{ccc}1& 2& 8\\ 8& 5& 6\\ 9& 3& 5\end{array}\right]$

then the obtained cipher text is$.($Note that $Z=25,0=26,1=27,2=28...$ Hint: Use modular arithmetic$)$
