An arithmetic and logic unit (ALU) performs integer and logic operations. Implement the logic of a simple ALU that performs 2-bit addition and subtraction. Assume that the operands are A1A0 and B1B0, and the output is C1C0. The operation code 0 has only one bit, which selects addition or subtraction.
