👉 In mathematics, a non-supporting set is a set that does not contain any elements of its own complement. This means that if we consider an element of our set as being in the set itself, then it cannot be part of the complement of the set. For example, let's say we have a set A = {a,b,c,d} and we want to find out which sets are not supporting. We can do this by checking each set that contains an element of its own complement
