Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the grammar: E -> E + E | E * E | ID, demonstrate a full Shift-Reduce parsing of the input string 'a + b * c'. Show each step and state of the stack and input.

💡 Hint: Focus on each action sequence and how it affects stack and input.

Challenge 2 Hard

Construct an SLR parsing table for a simple arithmetic grammar involving addition and multiplication with appropriate handling for conflicts. Explain your decisions.

💡 Hint: Think about necessary steps to avoid conflicts in parsing decisions.
