Consider the following variables

A $=[12345]$

B $=13$

C $=[133$; $239$; $947]$

D $=$ 'Text'

a$)$ Create a $2$x$2$ cell array with the provided variables. Save the result as Q$8\_$Array.

b$)$ In Q$8\_$Array, change the third character of the string variable from $\text{'}$x$\text{'}$ to $\text{'}$s$\text{'}.$ Do this

without recreating the entire array or altering the original variable D$.$

c$)$ In Q$8\_$Array, change the value in the third row, second column of the matrix to the

value $10.$ Do this without recreating the entire array or altering the original variable

C$.$

d$)$ Use built$-$in functions to combine the following cell arrays with Q$8\_$Array to create a

$3$x$3$ cell array called Q$8\_$Array$2.($Note: This may require multiple lines of code$)$

Array$1=\{[1234]$ ; 'Hello'$\}$

Array$2=\{17,15,[54321]\}$
