Top-Down Parsing/Exercise 13: Test 2016/04/08

< Top-Down Parsing


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
  1. Examine the grammar and rewrite it so that an LL(1) predictive parser can be built for the corresponding language.
  2. Compute the FIRST and FOLLOW sets for all non-terminal symbols in the new grammar and build the parse table.
  3. Show the analysis table (stack, input, and actions) for the parsing process of the bacy input sequence.
