Question
Consider the grammar G below in the input alphabet {num, *, /, -}, with non-terminal leading S' in rule 1.
- S'→S$
- S→E - F
- F→E * E
- E→num
- E→num / num
a) Build the G grammar automaton. Is this grammar LR(0)?
b) If G is not LR(0), list the items present in the DFA state where the conflict occurs.
c) Is this grammar SLR?
d) If G is SLR, write the non-terminal follow that resolves the LR(0) conflict. (Separate the items in the set with “:”. Ex: a:b )
