Which of the following algorithms utilizes Disjoint Set Union for its implementation?
Step 1: Understand what Disjoint Set Union (DSU) is. It is a data structure that keeps track of a set of elements partitioned into disjoint (non-overlapping) subsets.
Step 2: Learn about Kruskal's algorithm. It is an algorithm used to find the minimum spanning tree of a graph.
Step 3: Recognize that Kruskal's algorithm needs to manage and merge sets of vertices to avoid cycles while adding edges to the minimum spanning tree.
Step 4: Identify that Disjoint Set Union is used in Kruskal's algorithm to efficiently check if two vertices belong to the same set and to merge sets when adding edges.
