Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a CFG for an arithmetic expression language that includes addition, subtraction, multiplication, and division, ensuring it handles operator precedence appropriately.

💡 Hint: Think about how to group operations correctly to follow mathematical rules.

Challenge 2 Hard

Develop a recursive descent parser in pseudo-code for the grammar: E -> E + T | T, T -> ID. Ensure to handle expressions without left recursion.

💡 Hint: Remember to create your functions based on your grammar's productions.
