Webb26 feb. 2024 · For example, my textbook says the following RE can be simplified as such (U denotes the Union operation and the alphabet is {0,1}) (0 U ε)1* = 01* U 1* Shouldn't it just be 01* since ε is the empty string? Isn't it basically a concatenation of {0} and 1*? Also, is ε considered a symbol in an alphabet? WebbOnline regular expression tester (regex calculator) allows to perform various regular expression actions on the given text: .
