1. Consider the following grammar. A AaA a) What is the type of the grammar according to Chomsky hierarchy? Why? b) Find the language generated by the grammar. c) Design another grammar with a more restrictive type that generates the same language you found in (b). (e.g. if the given grammar is Type-1 then design a Type-2 or Type-3 grammar.) d) Is it possible to write a regular expression for the grammar you designed in (c)?
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>

Principles of programming languages: Write the BNF grammar for assignment statements written with any of the operators listed in the table below giving their precedence and associativity. The start symbol for the grammar is ASSIGN. Use the tokens ident and numlit wherever an identifier or numerical literal occurs in the appropriate rule. Note: Write your nonterminal symbols in all upper case letters. Don't use < and > in your answer since it causes problems with typing your answer. Precedence Operator Type Associativity 5 ( ) Parenthesis Left to Right 4 ! Unary logical negation Right to Left 3 == is equal to Left to Right 2 && Logical AND Left to Right 1 = %= Assignment Modulus assignment Right to Left
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by repeatedly replacing a non-terminal symbol by the right-hand-side production until all the non-terminal symbols have been replaced by the terminal symbols.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…

Problem 1: Write a regular expression that recognizes the following language over the alphabet {a,b}: Any string containing the letters a and b, where the number of letters is not a multiple of three. (Note that 0 is a multiple of three.) Your regular expression should contain only a and b, and the metacharacters (, ), *, +, ? and |. Problem 2: Write a context free grammar that recognizes language from Problem 1. Your start symbol should be named S.
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. Give a CFG (context-free grammar) in CNF (Chomsky Normal Form) that generates the same language, except possibly for the string A, as the following grammar: SAB AB →bAa A → aaB bb
Design a Grammar for the following transition diagram:
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.
2. Let L = {w|w E {0, 1}" and w does not contain 011 as a substring}. a) Give a Type-3 grammar for this language. b) Write the regular expression for this language.
Q1: Explain the concepts of ambiguity of a grammar. Take an example of your choice and show that the grammar is ambiguous. Draw the parse tree as needed. Q2: Select three flow control statements from C-programming, or from any other programming of your choice, and explain how the relevant grammars are written.
