SpletTo make one regular expression that defines the language L, turn all the words in L into boldface type and stick pluses between them. For example, the regular expression that defines the language L = {baa, abbba, bababa} is baa + abbba + bababa. If L = {aa, ab, ba, bb} the algorithm described above gives the regular expression aa + ab + ba + bb The … SpletQuestion: QUESTION 2 Which one is the grammar of the language {(aa) n>0}U {(bb)" n>0} ?
