21. The class of languages generated by finite automata is known as the class of regular languages . 22. Regular languages are commonly used to define search patterns and the lexical structure of programming languages.23. It means " people-regular language . " About half of the Danezaa people speak the language. 24. Every regular grammar describes a regular language . 25. "' Proof "': Every ?-regular language is recognized by a nondeterministic B�chi automaton; the translation is constructive. 26. In addition to regular language courses, a Language Self-Learning Center is available to students at Halberstadt, too. 27. While the linear languages that are regular languages are deterministic, there exist linear languages that are nondeterministic. 28. B�chi automata recognize the ?-regular languages . 29. Type-3 grammars generate the regular languages . 30. Computer scientists call any language that can be accepted by a finite state machine a "'regular language " '.
