Define what one might mean by properly nested parenthesis structures involving two kinds of parentheses, say (() and []. Intuitively, properly nested strings in this situation are ([]), ([[]D[O], but not ([)] or ((]]. Using your definition, give a context-free grammar for generating all properly nested parentheses.

C++ Consider the language that the following grammar defines: <S> = c | <W> | c<S> <W> = abb|a<W>bb Write all strings that are in this language and that contain seven or fewer characters. If the answer includes multiple strings, you must enter the answers in alphabetical order. A. In alphabetic order, what are the two strings in this language that are 3 characters in length? B. In alphabetic order, what are the two strings in this language that are 4 characters in length? C. In alphabetic order, what are the two strings in this language that are 5 characters in length?
Using the algorithm described in Section 4.4.2, remove direct left recursion form the following grammar rules. List all of the a (alpha) and B (beta) substrings. Provide the new A-rules and A'-rules based on the a and B substrings. A → Aa | Abc | bc | d
Hello, I'm struggling to understand this problem and its elements. Would you mind providing a comprehensive solution with detailed explanations and steps? It would greatly aid my comprehension if you could break it down into clear, labeled sections. Your assistance is sincerely appreciated.

(1) Fill the blanks to complete the following sentences that describe the relations between regular expression, regular language, and regular gramma. You can also use your own statements to describe the relations. there is an NFA machine to (i) A language L is regular (ii) A language L is regular (ii1)A language L is regular it. there is a regular expression r to it. there is a regular grammar G to it.
Context-Free Grammar (CFG)
For this exercise, we will work on a regular grammar to recognize a comment in a C++ or Java program. A comment starts with /* and ends with */ and anything else in between can be ignored. We won't consider the case of nested comments. Keep in mind that you can have any number of * characters at the beginning, at the end, and in between. • Write a regular grammar recognizing such comments. • Draw the finite state machine for this grammar. • Draw a table for this grammar such as the ones for table-driver scanners in the class notes and in the book.
