Consider the following grammar:

$SSa|b||$

i$)$ What does this grammar accept?

ii$)$ Build an LL$(1)$ parse table for this grammar. If such is not possible, clearly show the resulting conflict in the parse table.

$4.$ Consider the following grammar:

$SbA$

$AaA|lon||$

i$)$ What does this grammar accept?

ii$)$ Build an LL$(1)$ parse table for this grammar. If such is not possible, clearly show the resulting conflict in the parse table.

$5.$ Consider the following grammar:

$SI|wES|A\frac{,}{\frac{?}{?}}if$ statement $|$ while$-$expression$-$statement $|$ assignment statement

$I$iEtSO$\frac{,}{\frac{?}{?}}if-$expression$-$then$-$statement$-$optional else part

$A$ ven$\frac{\frac{?}{?}}{v}$ariable$-$equals$-$number

$Ev\frac{,}{\frac{?}{?}}$ variable

$OeS|lon\frac{,}{\frac{?}{?}}$ else$-$statement $|$ nothing $(i.e.$ optional else$)$

Build an $LL(1)$ parse table for this grammar. If such is not possible, clearly show the resulting conflict in the parse table.
