Question 1

What does the Pumping Lemma state about a regular language?

It cannot be empty.
It can be pumped.
It cannot be represented by a DFA.

💡 Hint: Think about the criteria established by the lemma.

Question 2

True or False: The Pumping Lemma can only apply to infinite languages.

True
False

💡 Hint: Recall that finite automata can recognize certain finite languages too.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Show that the language L={a^n | n is a prime number} is not regular using the Pumping Lemma.

💡 Hint: Focus on how p being prime affects division.

Challenge 2 Hard

Construct a proof using the Pumping Lemma that language L={ww | w in {0,1}*} is non-regular.

💡 Hint: Revisit how the symmetry in 'w' would be disrupted.
