NettetLeft recursion is eliminated by converting the CFG into a right recursive CFG. Example of Left Recursive Grammar CFG = X → Xα / β where β does not begin with an A. After Elimination of Left Recursion from CFG. Then, we can eliminate left recursion by replacing the pair of productions with- X → βX’ X’ → αX’ / ∈ Now the CFG is Right Recursive CFG Nettet1.08K subscribers. #LeftFactoring is a #Grammar transformation that factors out the common prefixes in productions.

If there are two different left inferences for the same result, this grammar is ambiguous and is called ambiguous grammar; otherwise it is called an unambiguous grammar.
