Question

state whether or not it is regular.

(1) All strings over the alphabet {a,b,d,l,r} that contain at least one of the words bad, bald, ball or bard.

If you claim the language is not regular, prove your claim using the Pumping Lemma.
If you claim the language is regular,
– Give a regular expression that matches exactly the strings in the language,
– Give a graphical representation of an NFA that recognizes the language,
– Convert the NFA into a DFA that recognizes the language, and
– Minimize the DFA, that is, convert it into an equivalent DFA with as few states as possible and present it in
graphical form.
