    Yes, it is called a N.C. (Normally Closed) Switch!
    What is input B doing all this time?

    So your friend wants you to do his homework for him and, in turn, you want us to do it for you.

    Classic.

    Would it be possible for the two of you to come up with at least an attempt as a solution that we can discuss?
