Show that a language that is described by a regular expression can also be generated by a context-free grammar. As a hint, consider each mechanism, such as using a basic form or forming the regular expression re1 ∪ re2 from the expressions re1 and re2, and show how this can be transformed into grammar rules that can be added to the grammars generating the collection of strings denoted by re1 and re2.

Determine whether or not the following languages are regular. If the language is regular then give an NFA or regular expression for the language. Otherwise, use the pumping lemma for regular languages or closure properties to prove the language is not regular. 1) L = { 0 n1 k : k ≤ n ≤ 2k} 2) L = { 0 n1 k : n > 0, k > 0 } È { 1 k0 n : k > 0, n...
