NFA to DFA Converter

Convert Non-deterministic Finite Automata to Deterministic Finite Automata using the subset construction algorithm.

📚 Understanding NFA to DFA Conversion

NFA (Non-deterministic Finite Automaton): Can have multiple transitions for the same input from a state, and can have ε-transitions.

DFA (Deterministic Finite Automaton): Has exactly one transition for each input symbol from each state, with no ε-transitions.

Final States: Every DFA must have at least one final state. A DFA state is final if it contains any NFA final state from the original automaton.

Subset Construction: Each DFA state represents a set of NFA states. The algorithm explores all reachable state combinations.
