Design a circuit that takes in two 3- bit signed integers. The circuit should follow these specifications: . If the two numbers have opposite signs and are both even, then the circuit will add the two values; otherwise, the circuit will subtract the two values. . You can use a maximum of one adder component and one subtractor component. You may use any other gates and/or components you wish, and you may also use splitters to make the connections to these components cleaner
