What sort of data do we track in Kruskal's algorithm, and which data structures do we use to track this data? What is the running time for typical implementations of these data structures?

Step 1
Specifically, we are interested in the edges that are included in the minimum spanning tree (MST) and ensuring that we do not form cycles when adding edges. Show more…

Choose the best answer. Kruskal's second (reverse-delete) algorithm can be implemented in overall time: a. Θ(m log n(log log n)³) where m is the number of edges and n is the number of vertices. b. Θ(n log n) where n is the number of vertices. c. Θ(w) where w is the sum of all edge weights. d. Θ(nα(n)) where α is the inverse Ackermann function and n is the number of vertices.
