Problema

Consider the following grammar, where S is the initial symbol and { a, b } is the set of terminal symbols: <text> S -> G b b | a a b | b G a G -> a </text>

  1. Compute the set of LALR(1) states for the grammar. Build the corresponding LALR(1) parse table.
  2. Show the parsing process for input baaabb (including the actions/gotos and the input and stack states). In case of conflict, assume YACC's behavior.
  3. Is this an SLR(1) grammar? Why?
