Q $5.($a$)$ Draw the Expression Tree for $(A**(\frac{B}{C}))+(D-(E+F)).$

$($b$)$ Label the nodes of the tree to generate the optimal target code.

$($c$)$ Generate the optimal machine codes for the expression where the available registers set is $\{R_0,R_1\}.$ The available instructions are as follows:

$ST{M}_i,R_j\frac{,}{\frac{?}{?}}{M}_i=R_j$

$LD{R}_i,R_j\frac{,}{\frac{?}{?}}{R}_i=R_j$

$LD{R}_i,M_j\frac{,}{\frac{?}{?}}{R}_i=M_j$

$ADD{R}_i,R_i,R_j\frac{,}{\frac{?}{?}}{R}_i=R_i+R_j$

$SUB{R}_i,R_i,R_j\frac{,}{\frac{?}{?}}{R}_i=R_i-R_j\frac{?}{M}$

$UL{R}_i,R_i,R_j\frac{,}{\frac{?}{?}}{R}_i=R_i**M_j$

$DIV{R}_i,R_i,R_j\frac{,}{\frac{?}{?}}{R}_i=\frac{R_i}{R_j}$

$LD{R}_i,R_j\frac{,}{\frac{?}{?}}{R}_i=R_j$

$ADD{R}_i,R_i,M_j\frac{,}{\frac{?}{?}}{R}_i=R_i+M_j$

$SUB{R}_i,R_i,M_j\frac{,}{\frac{?}{?}}{R}_i=R_i-M_j\frac{?}{M}$

$UL{R}_i,R_i,M_j\frac{,}{\frac{?}{?}}{R}_i=R_i**M_j$

$DIV{R}_i,R_i,M_j\frac{,}{\frac{?}{?}}{R}_i=\frac{R_i}{M_j}$
