FIRST and FOLLOW Calculate the FIRST and FOLLOW sets for the following grammar. S rightarrow BSA (1) S rightarrow CS (2) A rightarrow a A (3) A rightarrow C (4) C rightarrow c C (5) C rightarrow B (6) B rightarrow b B (7) B rightarrow epsilon (8) For FIRST sets (a) Do an initialization pass by applying FIRST sets rules I and II. (b) Do successive passes, on the grammar rules in the order they are listed and apply to each grammar rule FIRST set rules III, then FIRST set rule IV then FIRST set rule V In your answer, you should show the FIRST sets after each pass. For FOLLOW sets, you should do: (a) Do an initialization pass by applying FOLLOW sets rule I (b) Do one pass on all grammar rules, in the order they are listed, and apply to each grammar rule FOLLOW set rules IV and V. (c) Do successive passes on all grammar rules in the order they are listed and apply to each grammar rule FOLLOW set rules II and III until there is no change. In your answer, you should show the FOLLOW sets after each pass
