WebDefinition − A context-free grammar (CFG) consisting of a finite set of grammar rules is a quadruple (N, T, P, S) where. N is a set of non-terminal symbols.. T is a set of terminals where N ∩ T = NULL.. P is a set of rules, P: N → (N ∪ T)*, i.e., the left-hand side of the production rule P does have any right context or left context..

Context-free grammar G can be defined by four tuples as: G = (V, T, P, S) Where, G is the grammar, which consists of a set of the production rule. It is used to generate the string of a language. incoming call recharge for airtel
