Challenge Problems
Push your limits with challenges.
Question 1
Consider a language that consists of balanced parentheses and the empty string. Create a CFG to generate this language, then illustrate a derivation of the string '(()())'.
💡 Hint: Start with the empty symbol and systematically apply the grammar.
Question 2
How might error recovery differ between a simple syntax error and complex nested errors? Discuss how a CFG could aid in each scenario.
💡 Hint: Consider examples of common syntax errors in code.
