From regular expressions to deterministic automata
Derivatives of regular expressions correspond to state transitions in finite automata When a finite automaton makes a transition under input symbol a

Motivation: Given a pattern (regular expression) for string searching we might want to convert it into a deterministic finite automaton or nondeter-

We are going to construct regular expressions from a DFA by eliminating states When we eliminate a state s all the paths that went through s no longer
