从有穷自动机到正则语言
在上篇中我们了解到DFA与NFA的故事，从中我们初识了正则运算并且了解到其封闭性(虽然我还没有写完)，在本篇中我们将会里了解到正则表达式，进

DFA and NFA -- 1
Some understanding of the formal definition of DFA and NFA, as well as the proof of regular operation closure and the equivalence of DFA and NFA, that is, the story of DFA belongs to NFA, is the special case and regular story yet. Some insights into deterministic finite automata (DFA) For deterministic finite automatons, we can give the corresponding formal definition, borrowed here from the one given by professor in
