If I understand what you mean, then the answer to your question is "Yes, you
can use A and ~A simulatneously for this problem as separate inputs. You do
not need to show the inverter for A to make ~A". I hope this helps.

As a sidenote, when talking about Computer Engr, a Reg is a register, and
comp. tends to be used for Computer. This made your email a little
confusing initially. If you can please use symbols such as A and ~A in the
future, that will be more clear.

Thank you,
