WebWe have now finished the series concerning the basics of lexical analysis. We have defined regular expressions, the two sub-types of FAs and we have seen how we can convert between the two, as well as expressing a regular expression as both an NFA and a DFA. In the next articles, we will start talking about the basics of syntax analysis. WebDetail: This is an experiment of the principle of compilation.
