Welcome to the regular expressions/DFA/NDFA online exercises!

This package enables you to create regular expressions and automata to accept a given language, and then see where you went wrong. There are questions asking for regular expressions, DFAs, and NDFAs. You enter a solution to the posed question, the program figures out if it is correct, and tells you so.
