Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a Turing Machine for a language that accepts strings consisting of an equal number of 'a's and 'b's.

💡 Hint: Focus on how you would structurally implement the TM's transitions.

Challenge 2 Hard

Explain how the properties of non-deterministic Turing Machines change the perspective on language acceptance.

💡 Hint: Reflect on how exploration of multiple paths may help in certain scenarios versus traditional determinism.
