SOLVED: A CFG G = (E,T,F,I, , *, (, ), x, y, z, R, E) where the productions R are as follows:E -> E T; T -> T * F | F; F -> I | (E) | I(E); I -> x | y | z(a) (15pts) Compute the Chomsky Normal Form (CNF) for G(b) (10 pts) Compute the Greibach Normal Form (GNF) for G(Note that what is required is the precise definition of the GNF and not necessarily the form used for top-down parsing in class in which the first elements of the productions of a non-terminal variable are distinct!)
