Disjoint-Set Operation

Disjoint-Set Operation. Disjoint Set Operations? MAKE-SET(x)?Create new set {x} with representative x. UNION(x,y)?x and y are elements of two sets. Remove these sets and add their union. Choose a representative for it. FIND-SET(x)?return the representative of the set containing x.

Disjoint Sets

Disjoint Sets. CS2 -- 9/8/2010. Disjoint Sets. A disjoint set contains a set of sets such that in each set, an element is designated as a marker for the set. A simple Disjoint Set: {1}, {2}, {3}, {4}, {5} There is only one marker for each of these sets. The element itself.
