The Disjoint Set ADT Our second observation is that the name of the set returned by Find is actually fairly arbitrary.All that really matters is that Find(a)=Find(b)if and only if a and b are in the same set. Thus,one idea might be to use a tree to represent each set,since each element in a tree has the same root.Therefore,the root can be used to name the set.The Disjoint Set ADT ◼ Our second observation is that the name of the set returned by Find is actually fairly arbitrary.
