Figure 3.19 Chapter 3 REGULAR LANGUAGES AND REGULAR GRAMMARS Regular expressions Theorem 3.1 dfa or n Theorem 3.4 Theorem 3.3 Regular grammars We now have several ways of describing regular languages: dfa's, nfa's regular expressions, and regular grammars. While in some instanc one or the other of these may be most suitable, they are all equally powerful. Each gives a complete and unambiguous definition of a regular language. The connection between all these concepts is established by the four theorems in this chapter, as shown in Figure 3-19. K Construct a dfa that accepts the language generated by the grammar A ba B, B aAlbb. 2. Find a regular grammar that generates the language L (aa" (ab a) s. Construct a left-linear grammar for the language in Exercise 1 4. Construct right- and left-linear grammars for the language 2 3) 5. Adapt the construction in Theorem 3.4 to find a left-linear grammar for the language accepted by the nfa below Step by Step Solution
