I am tasked with creating a DFA for the regular language L = A/B, which are the strings that are in A but not in B. The alphabet is Σ = {a,b,c}
I am not really sure where to even start with this one, so any hints or suggestions would be much appreciated. I have never really encountered anything like this before. How do I represent "not in B". I have only dealt with more 'tangible' things, such as divisible by 5, ab(cb), etc. This doesn't really have a rule...I don't even know what the set B is.
