Please add explanation. PLEASE DONT COPY AND PASTE THE OTHER SOLUTION ON CHEGG BECAUSE IT ISNT THE FULL ANSWER
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. For example, the strings aaabbabbba, aaaababba, and aababbabb are in the language, while a, bba, ababb, aabaa, and bbaa are not. B) Draw the parse tree for string aabbaaba according to the previous grammar: C) Describe, in complete English sentences and “layman’s terms,” the language defined by the following grammar in BNF (start symbol is <S>):<S> ::= <A>a | <B>b<C> ::= c<A> ::= a<A>a | <C><B> ::= b<B>b | <C>
