Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the CFG productions, derive the string a + b * c using both leftmost and rightmost derivations. Explain your steps.

💡 Hint: Try expanding the non-terminals in both directions to see the differences.

Challenge 2 Hard
