The code for this post, as well as the post itself, are on github. This post is part 3 of a 3 part series. Part 1: Parsing Part 2: Generate an NFA Part 3: Evaluate an NFA Evaluating the NFA NFAs, DFAs and Regular Expressions Recall from part 2 that there are two types of finite automata: deterministic and non-deterministic. They have one key difference: A non-deterministic finite automata can have multiple paths out of the same node for the same token as well as paths that can be pursued with...
