Test: Right Left Linear Grammar - Computer Science Engineering (CSE) MCQ

The above stated grammar is non-linear because it has two non-terminals on the right-hand side.

Grammar is non-linear because one of the rules (the first one) has two non-terminals on the right-hand side.

Grammar is linear because no rule has more than one non terminal on the right-hand side.

Right-Linear grammars, following are the form of productions: A → xB or A → x where x is some string of terminals.

 grammars in which all of the rules contain only one non-terminal on the left-hand side, and where in every case that non-terminal is the first symbol are called right Linear.

 Linear grammar is of 2 types Left and Right Linear Grammar

In this case they both correspond to the regular expression (ab)*a.

As it turns out the languages that can be generated by Regular Grammars is equivalent to those that can be specified by Regular Expressions.

 That’s why they are called regular languages.

Since right-linear grammars are regular, it follows that left-linear grammars are also regular.

They are defined by rule A->b where A is non terminal and b is terminal.

Push Down Automata manipulate the Stack as a part of performing a transition.

Transition of finite automata is Finite Diagram.

When two or more Left and right most derivative occur the grammar turn ambiguous .
