A Union-Find Algorithm is a kind of algorithm that performs two important operations which are: Union and Find.
* The Union operation will combine or merge the two sets into one.
* The Find operation will which set is particular the element is in and is useful of determining if the elements are on the same set.
-- Here is a link that explains a brief implementation of the Union-Find algorithm:
