Now I know what that second figure means, it means it also accepts $\in$ as initial state=final state, but
how I don't know that. This dfa should accept all binary divisble by 4. But how is nothing(it is not zero mind that) divisible by 4?
Why I don't know that. I am making a dfa for binary numbers divisible by 4 and adiuni professor told that binary numbers that end with 00 are divisble by 4. So I googled about dfa ending with 00 and got this. I am personally more comfortable at first figure as it is more inituitive to me.
How is $\in$ divisible by 4? What does that even mean?
