GNF stands for Greibach normal form. So the grammar G2 is not in GNF. If the context free grammar contains left recursion, eliminate it. You can refer the following topic to eliminate left recursion: Left Recursion.
As the given grammar G is already in CNF and there is no left recursion, so we can skip step 1 and step 2 and directly go to step 3. JavaTpoint offers too many high quality services. Mail us on hr javatpoint. Please mail your requirement at hr javatpoint. Duration: 1 week to 2 week.
