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by repeatedly replacing a non-terminal symbol by the right-hand-side production until all the non-terminal symbols have been replaced by the terminal symbols.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…

1. Given the following grammar: E T(+T} T id [(num)] Write a recursive decent parser for the above grammar to check the syntax of an expression and generate its syntax tree
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>
1) LR sets and parser ======= Consider the following grammar describing Lisp arithmetic. Since all symbols are single characters, spaces have been omitted for compatibility with our input specifications for programming exercises 4 to 7 S -> E // S is start symbol, E is expression E -> (FL) // F is math function, L is a list // I is an item in a list L -> LI | I E I -> n // an item is a number n or an expression E F -> + | 1 * Find FIRST, FOLLOW and LR(0) sets for this grammar. Is the grammar LR (0)? Is it SLR?

Let G=(V, T, S, P) be the phrase-structure grammar with V= {0, 1, A, S), T = [0, 1] and a set of productions P consisting of S → 1S, S→ 00A, A → OA, and A → 0.
