Identify Context free languages using Pumping lemma

Choose difficulty:

Beginner

Intermediate

Advanced

What is the main purpose of using the Pumping Lemma in the context of context-free grammars?

a: To prove that a given language is context-free Explanation

Explanation

b: To generate new strings in a context-free language Explanation

Explanation

c: To eliminate ambiguity in context-free grammars Explanation

Explanation

d: To minimize the number of productions in a context-free grammar Explanation

Explanation

In the context of the Pumping Lemma, what does it mean for a language to be 'pumpable'?

a: The language contains repeated patterns Explanation

Explanation

b: The language can be generated by a finite automaton Explanation

Explanation

c: The language is context-free Explanation

Explanation

d: The language can be extended infinitely Explanation

Explanation

What role does the Pumping Lemma play in proving the non-context-freeness of a language?

a: It provides a set of pumpable strings for the language. Explanation

Explanation

b: It demonstrates that any string in the language can be 'pumped' to generate more strings. Explanation

Explanation

c: It guarantees that the language has a finite number of productions. Explanation

Explanation

d: It only applies to regular languages, not context-free languages. Explanation
