Give a CFG for each of the following languages with = {0, 1}.

(a) The regular expression 00*11*. (b) The complement of the language in (a). (Note: The complement of a language L with respect to the alphabet is the set * \ L, where \ denotes set minus.) (c) {w | the length of w is odd and its middle symbol is 0}. (d) {0ⁿ1²ⁿ | n 0}
