编译原理的课程设计报告中的手动词法分析构造器-Principles of curriculum design report compiled in a manual constructor lexical analysis

输入一个正则表达式，可以使用： 小写字母或数字，表示终结符；*，闭包；+，并集；~，补集；E，空串；O，空集 然后程序将生成 相应的NFA，以及化简之后的DFA，最后再输入一个字符串，程序判断它是否满足该正则表达式-input is a regular expression, you can use : lowercase letters or numbers, said Fu end;* Closure; , And set; To complement the set; E, empty string; O, empty set procedures will then generate the corresponding NFA, and the simplification of the DFA after finally lose into a string, procedures judgment whether it is to meet the regular expression
