In certain programming languages, comments appear between delimiters such as (# and #). • A comment must begin with (# and end with #). A comment may not contain #) inside the comment. • A comment's delimiters must be separate: (##) is a comment, (#) is not. For simplicity, assume that the alphabet is E = {a, b, (, ), #}). Give a regular expression that accepts comments.
