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.
Apr 19, 2024 · A data structure that stores non overlapping or disjoint subset of elements is called disjoint set data structure. The disjoint set data structure supports following operations: Adding new sets to the disjoint set. Merging disjoint sets to a single disjoint set using Union operation. Finding representative of a disjoint set using Find operation.

What is disjoint set Union (DSU) data structure?
Union-find, as it is popularly called, is a data structure that categorizes objects into different sets and lets checking out if two objects belong to the same set. The most popular usage of the data structure is to check whether one node in a graph can be reached from another, e.g. in the Kruskal's algorithm to avoid forming cycles.
Sep 22, 2023 · Last Updated : 22 Sep, 2023. A disjoint-set data structure is defined as one 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.
Oct 29, 2023 · A disjoint–set is a data structure that keeps track of a set of elements partitioned into several disjoint (non-overlapping) subsets. In other words, a disjoint set is a group of sets where no item can be in more than one set.
Mar 18, 2024 · In this tutorial, we’ll cover the Disjoint Set Union (DSU) data structure, which is also called the Union-Find data structure. Initially, we have a universe of elements: , and we’re interested in separating elements into independent (non-intersecting) sets.
Feb 15, 2024 · Disjoint sets are also known as disjoint collections or non-intersecting sets and refer to those sets which don’t have any identical element common between them. For example, A = {1, 2, a} and B = {3, 4, b} then, A ∩ B = ϕ. For this example, A and B are disjoint sets as both do not contain the same element. Disjoint Set Definition.
