rules satisfy the following pattern
where A, B, C V and a T.
Convert the grammar G = ({S, A, B, C}, {a, b}, S, P) with P given as

* 16. Two-standard form is general; for any context-free grammar G with λ L
(G), there exists an equivalent grammar in two-standard form. Prove this.

Grammars*
In Section 5.2, we claim, without any elaboration, that membership and parsing
algorithms for context-free grammars exist that require approximately
