Problem
Consider the following grammar, where A is the initial symbol and {a,b,c,d,e} is the set of terminal symbols:
X -> a A -> X c A e | M b M -> A c | X c d | (eps)
- 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 acbe input sequence.
