Question 1

Consider the language L={anbn+c+|nβ‰₯0} where 'b's follow 'a's and 'c's follow 'b's. Explain how this language might be structured and whether it’s DCFL.

πŸ’‘ Hint: Analyze the required stack operations.

Question 2

Design a DPDA for L={anbn|nβ‰₯0} and describe its transition rules in detail.

πŸ’‘ Hint: Visualize each step of the push and pop operations.
