Recall that the ALU accepts two 32-bit data operands as inputs and performs some operation using the two inputs to generate the ALU outputs

a) Explain how the ALU can use addition to determine if the 32-bit value in the rs register is less than the 32-bit value in the rt register.

b) Explain how the ALU can determine if the 32-bit value in rs equals the 32-bit value in rt without using subtraction or addition.
