From 0 to 1 Data Structures & Algorithms in Java - Implementation Of Kruskal's Algorithm

The video tutorial explains Kruskal's algorithm for finding a minimal spanning tree in an undirected graph. It covers the necessary data structures like Edge Info and Vertex Info, and details the setup process involving a priority queue and edge map. The tutorial then describes the algorithm's logic, focusing on edge selection and cycle detection using the hash cycle method. The goal is to ensure the spanning tree is minimal and connected without forming cycles.

How does the Edge map help in tracking the edges added to the spanning tree?

In what way does the algorithm ensure that the spanning tree is connected?

What is the significance of the visited vertices list in Kruskal's algorithm?
