Union(3, 4); System.out.println(uf.Find(3)); // after join, 3's parent is 4. } } This Java code prints 3 and 4. C++ Disjoint Set / Union Find Algorithm Implementation Similar, here is the C++ implementation of the Disjoint Set data structure. The union is a keyword in C++ and...
implementation of set_union To union two set, we just need to attach one set's representative number to the other set's parent: public void set_union(long i, long j){ i = find(i); j = find(j); parent[j] = i; } The time for set_union(long i, long j) is Tsetunion=2T...
We are done with the DSU implementation, its that easy. To check if two elements are in the same set or not just find their representative using find() and if they are same they belong to the same set. However our implementation is not much efficient, consider the below case...
The union operation combines two sets into a single set, while the find operation returns the representative element of a set.The implementation of the union-find algorithm involves maintaining a set of parent pointers and a rank for each element in the set. The parent pointer of an element ...
Implementation void make_set(int v) { parent[v] = v; rank[v] = 0; } void union_sets(int a, int b) { a = find_set(a); b = find_set(b); if (a != b) { if (rank[a] < rank[b]) swap(a, b); parent[b] = a; ...
The algorithm runs in near-linear or linear time, depending on the implementation of the disjoint set data structure. We give several versions of the algorithm, including one that computes loop nesting information (needed in many kinds of global code optimization) and that can be made self-...
