EBNF grammar for a concert calendar · You may assume that the tokens date, time, word and num have already been defined · A concert calendar is a list of concert events, where each event includes: • A date and time • The name of the performing group or artist, optionally followed by "(21+)" if there is a minimum age requirement to see the concert • A pipe (|) character • The name of the venue where the concert will be held, like "Pavilion" or "San Jose Ritz" • A pipe (|) character • The city where the venue is located • The price, possibly followed by a + if there are also more expensive tickets.

A = A * (B + (C * A)) b. B C* (A * C+ B) с. А - А * (В + (C))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by repeatedly replacing a non-terminal symbol by the right-hand-side production until all the non-terminal symbols have been replaced by the terminal symbols.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. (a) Write the prefix form for the expression a *- ( b + c ) (b) Write an SDD for the following grammar, which converts infix expressions to prefix expressions. E -> E + T | T T -> T * F | F F -> id | (E) 2. Write the quadruples, triples, and indirect triples for the following expression - (a+b)*(c+d) - (a+b+c)3.)Function composition We can define a higher order function, i.e. functional form, that accepts two functions as parameters and returns their sum, As an example, consider two functions below: f1(x) = x + 2 g1(x) = 3x + 4 These are modeled by the following Scheme functions, respectively: (define (f1 x) (+ x 2)) (define (g1 x) (+ (* 3 x ) 4)) The higher order function plus = f1 + g1: (define (plus func1 func2) (lambda (x) (+ (func1 x) (func2 x)))) Note the use of the lambda in order to return a nameless function. In essence, we are accepting two functions, func1 and func2, and returning a function that takes one parameter x and represents their sum. We can apply this functional form as follows: ((plus f1 g1) 10) ; returns 46. Or (define (plus func1 func2 x) (+ (func1 x) (func2 x)) ) (plus f1 g1 10) ; returns 46. Define a function (form) that compute the product of two functions and test your functions.1. a) Design a context free grammar for the following language. L = { 0*1" |m,n >=0, n !=m }
