With the definitions of FIRST being the set of terminal symbols that begin strings derived from α, and FOLLOW being:
FOLLOW(A) = { a | S ⇒* αAaβ }
What are the FIRST and the FOLLOW sets for the following grammar?
E1 → E2F1end
F1 → +E1 | ε
E2 → numF2
F2 → *E2 | ε
I'm thinking:
FIRST(E1) is {num}
FIRST(F1) is {+, ε}
FIRST(E2) is {num}
FIRST(F2) is {*, ε}
Not a clue for the the follow sets though.
