Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a CFG for balanced parentheses, derive the string (()(())) and illustrate the derivation process with a parse tree.

💡 Hint: Begin from the start symbol and apply rules step by step.

Challenge 2 Hard

Explain how the CYK Algorithm works when given a string 'ab' and a specific grammar in CNF. Illustrate the parsing table.

💡 Hint: Remember to break down the string into smaller parts and analyze them systematically.
