WebCFG stands for context-free grammar. It is is a formal grammar which is used to generate all possible patterns of strings in a given formal language. 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. WebCFG for the language of all non Palindromes. CFG for strings with unequal numbers of a and b. CFG of odd Length strings {w the length of w is odd} CFG of Language contains …
