Create a cfg describing regular expressions over the alphabet {0, 1}. you will need to quote the regular expression operators and the template given you has them quoted as terminals. we expect the grammar to generate the following syntactic constructions:
• union via "|", for example, 0 1 "|" 1 should be in the language generated by the grammar
• intersection via "& ", for example, 0 1 "& " 1 should be in the language
• concatenation: any nonempty sequence of regular expressions should be in the language
• the empty string, which is denoted with the terminal e. for example, 0 "|" e should be in the language
• parentheses: for example, "(" 0 1 ")" should be in the language • kleene star: for example, "(" 0 1 ")" "*" should be in the language
• complement: for example, "-" "(" 0 "*" ")" should be in the language
