First, the algorithm initialises an array which stores the initial distance from 0 to all other nodes. The distance to all other nodes is set to positive infinity. Then the algorithm creates a priority queue and enqueues the key-value pair <0, 0>. Then it dequeues it. how to open odm audiobook murphy beds in mn

"WebThe sum of all weights of each edge in the final MST is 6 (as a result of 3+2+1). This sum is the most minimum value possible. Let the number of vertices in the given graph be V and the number of edges be E. In Kruskal's algorithm for MST, we first focus on sorting the edges of the given graph in ascending order.
