Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a DFA that recognizes strings containing an odd number of '1's over the alphabet {0, 1}. Explain your choice of states and transitions.

💡 Hint: Consider how the state changes with each input symbol.

Challenge 2 Hard

Using the Pumping Lemma, prove that L = {a^n b^n | n ≥ 0} is not a regular language.

💡 Hint: Think about what happens when you try to pump 'y'.
