Question 16
Consider the following statements about Deterministic Finite Automata (DFA) and Nondeterministic Finite Automata (NFA).
Which of the following statement(s) is/are correct?
There exist languages that can be accepted by an NFA but not by any DFA.
An NFA accepts an input string if at least one computation path reaches an accepting state after reading the entire input.
A DFA has exactly one transition for every input symbol from each state.
An NFA accepts an input string only if all possible computation paths end in accepting states.
Every language accepted by an NFA can also be accepted by a DFA.
