Problem 2 (Programming Language) In certain programming languages, comments appear between delimiters such as /# and #/. Let C be the language of all valid delimited comment strings. A member of C must begin with /# and end with #/ but have no intervening #/. For simplicity, assume that the alphabet for C is Σ = {a, b, /, #}. (a) Give a DFA that recognizes C (b) Convert the DFA from part (a) to an equivalent Regular Expression
