| = Problem =
| |
| | |
| Consider the following grammar, where '''<tt>A</tt>''' is the initial symbol and '''<tt>{v,x,y,z}</tt>''' is the set of terminal symbols:
| |
| | |
| C -> v
| |
| A -> B x | z C A y
| |
| B -> A v | z C w | (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 '''<tt>zvxy</tt>''' input sequence. | |
