week 10 -Regexes, FSAs

This week we did DFSA and a little of regex algebra. I wonder how important regex algebra will be in this course. But as for DFSA, I didn't really understand what the state invariant meant. But after i read the course notes and understood it better. It's just like a description and it describes how the system moves from the initial state to another state.

However, i didn't really get what the example with the multiples of 3 in base 2 meant. Shall have to go through the part about the x1 and x0 parts again.
