28 jui 2021 · Regular Expressions are used to denote regular languages (b + ab)*a covers all cases of strings generated ending with a
How do you generate regular grammar to regular language?
Consider the regular expression (a + b)*a. We will now construct a regular grammar for this regular expression. For every terminal symbol a, we create a regular grammar with the rule S \\arrow a, start symbol S. We then apply the transformations to these regular grammars, progressively constructing the regular grammar.Which grammar generated regular language?
The regular language can be described as a language that is generated by the type 3 grammar and for which finite automata can be designed.What language does the regular expression AAB * aB )* represent?
Hence a string of L consists of zero or more aab's in front and zero or more bb's following them. Thus (aab)*(bb)* is a regular expression for L.- A language generated by a CFG is a context-free language (CFL).
