Problem
Consider the following grammar, where A is the initial symbol and {x, y, z} is the set of terminal symbols:
A → B y | x | ε
B → A x | C z
C → x | ε
- 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 xzyxy input sequence.
