Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Construct a CFG that generates the language of correctly nested parentheses, and explain each production rule.

💡 Hint: Think about how each rule represents the structures.

Challenge 2 Hard

Describe a situation where the need for CFGs arises in real-world applications, and how they overcome the limitations of regular expressions.

💡 Hint: Consider coding examples that require hierarchical representation.
