1. Intersection is not closed over the class of context-free languages, i.e., the intersection of two context-free languages is not guaranteed to be context-free. However, intersection with a regular language is closed over the class of context-free languages, i.e., the intersection of a context-free language and a regular language is guaranteed to be context-free. Prove that intersection with a regular language is closed over the class of context-free languages using a proof by construction. hint: You will want to provide a construction using PDA.
