Consider the following grammar, where A is the initial symbol and { x, y, z } is the set of terminal symbols:  
<text>
A -> B x y | x y x | x B y
B -> z | ε
</text>
# 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 '''xzy''' (including the actions/gotos and the input and stack states). In case of conflict, assume YACC's behavior.
