Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Using the string 'xy' and the grammar rules: S → AB, A → x, B → y, demonstrate the table filling process for the CYK algorithm.

💡 Hint: Break down each entry systematically while considering the rules.

Challenge 2 Hard

Identify a grammar that cannot be parsed using the CYK algorithm, providing reasoning.

💡 Hint: Consider the implications of having rules that aren’t structured properly.
