Push your limits with advanced challenges

Challenge 1 Hard

Formulate a detailed demonstration that proves the Empty Language Problem is undecidable using the Halting Problem.

💡 Hint: Remember the loop structure that features in each problem's essence.

Challenge 2 Hard

Establish how Rice's Theorem could be used to prove undecidability for properties of languages like being infinite.

💡 Hint: Focus on examples of languages showing contrasting properties.
