WebbAmbiguity in Grammar. A grammar or a Context-Free Grammar (CFG) is said to be ambiguous if there exists more than one leftmost derivation (LMDT) or more than one rightmost derivation (RMDT), or more than one parse tree for a given input string. Technically, we can say that context-free grammar (CFG) represented by G = (N, T, P, S) … WebbCFG is a helpful tool in describing the syntax of programming languages.
