What are advantages of full subtractor?

A full subtractor is advantageous because it can handle the subtraction of binary numbers while accounting for borrow from previous bits, allowing for accurate multi-bit subtraction. It requires only three inputs (two minuends and a borrow-in) and produces two outputs (the difference and borrow-out), simplifying circuit design. This efficiency makes it suitable for digital systems like ALUs in processors. Additionally, full subtractors can be easily cascaded to create larger subtractors for handling more significant binary values.
