Problem
Consider the following grammar, where B is the initial symbol and {a, b, c, x, y} is the set of terminal symbols:
X → c A → a A | B x | X B → b B | A y
- Examine the grammar and rewrite it so that an LL(1) predictive parser can be built for the corresponding language.
- Compute the FIRST and FOLLOW sets for all non-terminal symbols in the new grammar and build the parse table.
- Show the analysis table (stack, input, and actions) for the parsing process of the bacy input sequence.
