If the State array contains $128$ bits of data: $1B37$ AB $4B72$ F$66$B E$3$ A$7$ A$3392485734D23($in hex$)$ before the first round in AES,

$($a$).$ write the corresponding $44$ byte matrix $(3$ points$)$

$($b$).$ what will the $44$ byte matrix in $($a$)$ look like after the first step of Byte Substitution operation in round $1.(5$ points$)$

$($c$).$ what will the $44$ byte matrix in $($b$)$ look like after the second step of row shifting operation in round $1(5$ points$).$

$($d$).$ what does the State array contain after $($c$).(3$ points$)$
