Jan 17, 2026 · It takes two elements as input and finds the representatives of their sets using the Find operation, and finally puts either one of the trees (representing the set) under the root node of the …

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 …

Find an algorithm to solve it. Fast enough? Fits in memory? If not, figure out why. Find a way to address the problem. Iterate until satisfied.

Dec 15, 2025 · To combine two sets (operation union_sets(a, b)), we first find the representative of the set in which a is located, and the representative of the set in which b is located. If the representatives …

Jun 13, 2025 · The Union-Find algorithm is used for managing a set of elements partitioned into disjoint subsets. It's particularly useful in graph theory, network connectivity problems, and finding …

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.

Union-Find is a key component in Kruskal’s algorithm for finding the minimum spanning tree of a weighted, undirected graph. This has applications in network design, clustering, and image …

Sep 19, 2025 · This post explains the working of disjoint-set data structure (also called union find data structure). A disjoint-set is a data structure that keeps track of a set of elements partitioned into a …

Picture the Union-Find algorithm as a detective looking for hidden cycles within a network of interconnected nodes. Let's walk through a real-world example to see how this algorithm can unveil …
