Answer both parts. Thanks

Start with the grammar below:
G6:
<exp> :: = <exp> + <mulexp> l<mulexp>
<mulexp> ::= <mulexp> * <rootexp> | <rootexp>
<rootexp> :: = (<exp>)| a | bl c
Modify it in the following ways:
a, Add subtraction and division operators (- and/) with the customary precedence and associativity.
b. Then add a left-associative operator % between + and * in precedence.

give an unambiguous grammar for the same language.

Find context-free grammars for the following language: L = anbn, n is even.
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.

1. Use the algorithm described in class that takes a CFG and converts it into a CNF (Chomsky Normal Form) grammar that generates the same language as the original grammar, except possibly for the string A, to answer the following question. As part of your answer, you should say which variables are nullable, and you should give the appropriate grammar after each step of the algorithm. There are four steps.

a. Write a BNF grammar for the language consisting of strings built only of the letters a and b. The strings may have any number of these letters, but the letter combinations bb must be in each string somewhere, and each string must start with a aa.
