   +----DataStructures.DisjSets
public class DisjSets
extends Object
Disjoint set class, using union by rank and path compression. Elements in the set are numbered starting at 0.

Constructor Index

o DisjSets(int)
Construct the disjoint sets object.

Method Index

o find(int)
Perform a find with path compression.
o main(String[])
o union(int, int)
Union two disjoint sets using the height heuristic.

Constructors

o DisjSets 
  public DisjSets(int numElements)
Construct the disjoint sets object.

Parameters:
numElements - the initial number of disjoint sets.

Methods

o union 
  public void union(int root1,
                    int root2)
Union two disjoint sets using the height heuristic. For simplicity, we assume root1 and root2 are distinct and represent set names.

Parameters:
root1 - the root of set 1.
root2 - the root of set 2.
o find 
  public int find(int x)
Perform a find with path compression. Error checks omitted again for simplicity.

Parameters:
x - the element being searched for.
Returns:
the set containing x.
o main 
  public static void main(String args[])
