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?
Design the NFAS that recognize the following languages. L1 = {abc, abd and aacd), assume the alphabet is {a, b, c, d}. L2 = The set of all strings containing no four consecutive a's and having even number of a's & odd number of b's defined over the alphabet {a, b}.

arrow_forward Step 1 Context Free Grammar: A formal language that is used to generate all possible strings in a given formal language is called context free grammar. It can be defined as: G=(V, T, P, S) Where G specifies the grammar V specifies the finite set of non-terminal symbols. T specifies the finite set of terminal symbols. P specifies the set of production rules. S specifies the start symbol. The start symbol S is used to derive a string in a context free grammar. It is derived by repeatedly replacing a non-terminal symbol by the right-hand-side production until all the non-terminal symbols have been replaced by the terminal symbols. arrow_forward Step 2 G is a context-free grammar for a language L, and L contains only strings of length 2 or greater. We have to prove that there is a context-free grammar Gd which generates L such that every rule in Gd has the form A -> x1x2, where A is a terminal and each xi is a terminal or a non-terminal. Let the alphabet of…
3. Given the following BNF grammar: -> d c | cd -> a la -> b | b Use the top-down recursive descent method which we discussed in the class to implement a parser (i.e. tdrd.parser.py) in python3 for the above BNF grammar. The input data file name is given from the command line. You may assume that there is a space character between two terminals (e.g. a a adc b ) in the data file.
Rewrite the following EBNF grammar in BNF. <decl> → <ident_list> : (int | float | char); <ident_list> → <identifier>{,<identifier}.
Q1: Write a grammar for the language that includes all strings containing n copies of alphabet a, followed by n+1 copies of the alphabet b. Assume ? > 0. Upon completion of the grammar definition, draw the parse tree for the sentences abb and aabbb along with the derivations.Q2: Consider the identifier definition of a hypothetical programming as follows: strings of consist of letters and numbers, and they must begin with a letter.
Chomsky Normal Form: Most useful grammars can be translated into a nor-mal form making answers to questions about the language more transparent.
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>
