Separately, either "Union by Rank" or "Path Compression" improves the running time of the operations on disjoint-sets. Alone, "Union by Rank" yields a running time ofO(m log n), wheremis the number of Union and Find-Set operations andnis the number of sets. ...
The valid operations are to make a new set with one element v, called Make-Set(v); and to take a union over two sets called as union(v1,v2). As an example, Make-Set(7) will make the sets as A = {1,4,5}, B = {2,3}, C = {6} and D = {7}. Further, taking union...
