(c) Draw a circuit to perform subtraction of two positive numbers [Opipapsl and [0gi92q3] (the pi and qi are binary digits) in this system. Stipulations Please clearly label all inputs. You may (read: please do) use half-adders as "black boxes" in your circuit in addition to the usual AND, OR, NOT, and NAND gates, with the usual number of inputs and outputs. You may not just hardcode behavior for all possible inputs - the TAs don't want to check 64 different paths. Instead, implement this as a computer would, using two's complement as a tool. Also, briefly explain at a high level how your circuit works (imagine you are writing a comment in your code).
