HS -half subtractor
FS -full substractor
i understood that we solve these kind of questions not by imaganing the subtructions of a number
but by using the formulas of B and D
i tried to implement that in this question
and i figured out how to create Z1 and Z0 bit using HS
(there is a typing mistake instead of Z2 its Z0)
but the Z3 and Z2 formulas consists of OR gates and they are much longer
so i cant imagine how to split these long expressions into the small formulas of D and B
