Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a new grammar to represent mathematical expressions that eliminates ambiguity and account for both precedence and associativity for all four basic operations (+, -, *, /).

💡 Hint: Focus on how you can break down the operations into non-terminals to control precedence.

Challenge 2 Hard

Discuss the implications of using an ambiguous grammar in software development, citing historical examples or theories.

💡 Hint: Consider the impact on large-scale projects.
