We then present an algorithm to convert a CFG to a language-equivalent PDA in Section 14.3, and an algorithm to convert a PDA to a language-equivalent CFG in Section 14.4. This latter algorithm is non-trivial - and so we work out an example entirely, and also show how to simplify the resulting CFG and prove it correct. In Section 14.5, lithograph effect photoshop
