Follow-up Question
Sorry to ask about this BNF grammar again, but what would the LR(1) sets be if the parentheses and bracket symbols were terminal symbols?
E::= V | F
V:= id | id[E]
F:= id(E)
Solution

Follow-up Question
One last question. For this same grammar, would the LR(1) sets be different if both the parentheses and bracket symbols were treated as terminal symbols?
Ex: FOLLOW(E) = { ], ), $ }
E::= V | F
V:= id | id[E]
F:= id(E)
Solution

Follow-up Question
Would the sets be the same if the characters were spaced out?
E::= V | F
V::= id | id [ E ]
F::= id ( E )
