Problema

Consider the following grammar, where E is the initial symbol and { [, ], ;, id } is the set of terminal symbols: <text> E -> [ E ; L ] | id L -> E | E ; L </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 [id;id;id] (including the actions/gotos and the input and stack states). In case of conflict, assume YACC's behavior.
  3. Is this an LL(1) grammar? Why?
