The following is a list of statements about deterministic finite automata and regular languages.
Select all statements from below that are true.
Suppose language Lis regular. If a DFA M recognizes L, then for any string w e E*, M will decide
whether w E Lafter exactly w| transitions.
O A valid DFA may have unreachable states.
Suppose there are two DFAS that recognize languages L and L2, respectively. It may be the case that
Lin L2 is regular, but it is also possible that this language is not regular.
O For a DFA M
(Q, E, 8, qs, F), it may be the case that e e E.
O The transition function 8 of a DFA may be continuous.
