Regular expression to NFA-confusing regular expressions-:

[shivajikobardan]

R=(01+010)*

For it I made the below nfa which i believe seems correct. Plus the tutorials that I am following also make sure it’s correct. Q0 is initial state(forgot to mention in figure).

 

R=(01)*+(010)*

 

But idk how to convert this to NFA

What will be languages accepted by this NFA? Won’t it be the same as the above one? 

 

(for some different question)

I got small hint about this. It was to add epsilon transition, but I don’t understand the need for it.
