Using the alphabet = {a, b, e, (, ), +, *} (Note that "e" stands for the character of epsilon, to distinguish it from the empty string, . Also note that the left parenthesis and right parenthesis are letters in this alphabet) Then create a CFG that generates valid regular expressions. For example, the CFG could generate the word a+(bb)*, or abb*(aa+e). Is the language generated by the grammar you just constructed regular? Why or why not?
