Which one of the following is true about regular languages?
A regular language can contain an infinite number of strings
A regular language must contain an finite number of strings
A regular language can parse a context-free grammar
A regular language cannot be expressed with regular expressions
Write 3 strings that this regular expression matches((b|c)a(d|t))*
Write a regular expression for the following language description: zero or more letters “a” followed by either letter “c” or letter “d”.
Convert this regular expression to a nondeterministic finite automaton (NFA)(aba|bab)*c
Convert the NFA above into a deterministic finite automaton (DFA)
