NFA recognizing

Problem 1

Consider language L equal to the set of strings on the alphabet {a, b} such that the final symbol in the string has not appeared earlier in the string. Some strings in L include e, a, ab, aab, b, ba, and bba(there are infinitely many others of course).

(a) Draw a DFA that recognizes language L. (You may wish to draw an NFA recognizing L and then convert this to an equivalent DFA, but this approach is not required.)

(b) Write a regular expression that generates L.Make the regular expression as simple as possible.
