Question 1

What describes an NFA?

1. A deterministic machine with one path for each input.
2. A non-deterministic machine that can have multiple transitions.
3. An automaton that cannot accept any strings.

💡 Hint: Think about the flexibility of transitions.

Question 2

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a specific Regular Expression, construct an equivalent NFA and explain each step of the process.

💡 Hint: Focus on identifying the patterns and how they connect.

Challenge 2 Hard

Explain the mathematical basis of why NFAs and DFAs are equivalent using both conversion methods.

💡 Hint: Map the states from NFA to DFA visually to help with the explanation.
