Question

Hello, I am stuggling with this specfic problem and the specific parts as well, can you please help me get a solution for this problem. I only need help with part B and part C because I don't understand how to do those problems.

Can you please show the regular expression to NFAs in a visual representation thank you.

Again I only need help with part B and C and can you label the parts as well, so I know which part is part B and which one is part C.
