LL/LR-automaton
In order to illustrate the amount of freedom that ex-
ists for the construction of automata and associated
parsers, we shall construct a non-deterministic LL/LR-
automaton and ... accordingly to be the smallest one
that satisfies
ctos,,re({Xo"°}) E Q^ (s E q
=~

z) C q))
Every state in this automaton...
