Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the production rule A -> B C, illustrate a scenario where the nodes are incorrectly matched leading to a syntax error. What would the stack contain?

💡 Hint: Look at how many symbols are on the stack compared to what is expected by the grammar.

Challenge 2 Hard

Construct a parsing table for a simple grammar with three rules: S -> A B, A -> 'a', B -> 'b'. Explain how it would inform the parser's actions on the input 'ab'.

💡 Hint: How will each step on the input influence the state transitions?
