Introduction The Union Find data structure stores a collections of disjoint (non-overlapping) sets and can be used to model connected components in undirected graphs. This data structure can be used to: determine if two vetices belong to the same component detect cycles in a graph find the minimum spanning tree of a graph Union Find Implementation Optimized Union Find (Disjoint Set) python implementation with path compression and union by rank....
