1. These exercises do not score in the final grade. Therefore, you can freely discuss them in the Forum without worrying about whether you are transgressing the Honor Code. The algorithm in figure 1 computes P-X-Y where X and Y are n-bit and m-bit numbers respectively. The first step to implement the algorithm is to build a basic module that executes the "OnebitMultiplier" procedure (figure 2). What circuit implements the basic component shown in figure 2? (hint: (a NAND b) NAND (e NAND d) NAND (e NAND f) ab+cd+c.f) acc
