Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a DFA that recognizes the concatenation of two languages L1 = {a, b} and L2 = {0} and explain each step in your construction.

💡 Hint: Think of how transitions work individually for each part.

Challenge 2 Hard

Prove the concatenation closure property formally using an example language.

💡 Hint: Narrow down your steps in constructing the related DFAs.
