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...
5. Return the updated disjointness and the linked list. Here is the Python code for the implementation: ```python class Node: def __init__(self, value): self.value = value self.next = None class DisjointSet: def __init__(self): self.head = None self.size = 0 def add(self, val...
The Union Find (Disjoint Set) Implementation in Java The Union-Find (Disjoing Set) is a commonly-used algorithm that can solve e.g. Minimal Spanning Tree. The following is a Java implementation of a Union-Find Class.
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...

Sample SPOJ Problem and Implementation (video version:https://youtu.be/O4w-aX5mSks?si=vr0XSbyUswcXx-Yv) Upcoming Practice Problems Some Applications and References We will learn about disjoint set data structures and their operations union and find through a sample problem. ...
Assume that the size of one element set is 1 and store – 1. Other than this there is no change. Implementation void make_set(int v) { parent[v] = v; size[v] = -1; } void union_sets(int a, int b) { a = find_set(a); ...
