Compiler DesignGiven a context-free grammar (CFG), compute FIRST and FOLLOW sets for all non-terminals, and construct the LL(1) parsing table. Also, determine whether the grammar is LL(1) or not. Grammar: S \rightarrow A B A \rightarrow a A | \epsilon B \rightarrow b B | \epsilon20247m Compiler DesignShow that the following grammar is LL(1) but not SLR(1). S \rightarrow AaAb/BbBa A \rightarrow \epsilon B \rightarrow \epsilon20236m Compiler DesignCompute FIRST and FOLLOW for the given grammar. Also derive the LL(1) parsing table.
