When dealing with strings, exponents denote repetition. For example, a²=aa, a³=aaa, aⁿ= n a's. Construct a DFA over {a,b} that recognizes the language of all words ending in a^xb^y, where x and y are both odd. (Assume that a^x includes the entire group of a's. For example, aaaa can only be counted as a⁴, and not as a single 'a' followed by a³). Minimize your DFA or ensure that it's already minimal.
