Problema
Consider the following grammar, where S is the initial symbol and { e, i, x } is the set of terminal symbols:
S → i S | i S e S | x
- Compute the set of LALR(1) states for the grammar. Build the corresponding LALR(1) parse table.
- Compact the parse table, eliminating and propagating reductions.
- Show the parsing process for input ixixex (including the actions/gotos and the input and stack states). In case of conflict, assume YACC's behavior.
- Is this an SLR(1) grammar? Why?
