Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
