Expert
It is the set of strings that lead to “accept” is the language recognized by this machine.
If every string that does not lead to accept leads to “reject”, then this language is decided by the machine.

State the Formal desrciption of DFA operation ?
Explain briefly NFA operation with example.
Proof the theorem that the class of regular languages is closed under union; that is, if L1 is recognized by a NFA and L2 is recognized by a NFA, then L1 υ L2 is recognized by a NFA as well.
Define the term Regular expressions ?
Let α be a regular expression of length n. (a) Using procedures shown in class, if we convert α into a regular expression β such that L(β) = L(α). How long β might be? Give a reasonably tight upper bound.

Let REGEXP be the language of valid regular expressions over {a, b}. That is, REGEXP is the set of all strings over the symbols Σ= {a, b, (,), U,*, ^} that are valid regular expressions. For example, the string “a (a U b)" is in REGEXP, whereas the string
