Is disjoint-set a data structure?

In computer science, a disjoint-set data structure, also called a union–find data structure or merge–find set, is a data structure that stores a collection of disjoint (non-overlapping) sets. Equivalently, it stores a partition of a set into disjoint subsets.

What is disjoint algorithm?

A disjoint-set data structure is a data structure that keeps track of a set of elements partitioned into a number of disjoint (non-overlapping) subsets. A union-find algorithm is an algorithm that performs two useful operations on such a data structure: Find: Determine which subset a particular element is in.

How do you find the disjoint-set?

Tree : It is a disjoint set. If two elements are in the same tree, then they are in the same disjoint set. The root node (or the topmost node) of each tree is called the representative of the set. There is always a single unique representative of each set.

What is disjoint-set with example?

What is a Disjoint Set? A pair of sets which does not have any common element are called disjoint sets. For example, set A={2,3} and set B={4,5} are disjoint sets. But set C={3,4,5} and {3,6,7} are not disjoint as both the sets C and D are having 3 as a common element.

Why do we use disjoint-set data structure?

1)It is used to keep track of connected component in an undirected graph. 2)It is used to detect cycles in the graph. 3)It is used to calculate the minimum spanning tree in Kruskal’s algorithm. 4)It is used in Maze generation problems.

What is disjoint-set operations?

Disjoint Sets | Disjoint set operations in daa A tree is used to represent each set and the root to name a set. Each node points upwards to its parent. Two sets A and B are said to be disjoint if A – B = f. i.e., there is no common element in both A and B. A collection of disjoint sets is called a disjoint set forest.
