WebPractice this problem. We know that Breadth–first search (BFS) can be used to find the shortest path in an unweighted graph or a weighted graph having the same cost of all its edges. BFS runs in O (E + V) time, where E is the total number of the edges and V is the total number of vertices in the graph. But if the edges in the graph are ... WebThe adjacency matrix is a good way to represent a weighted graph. In a weighted graph, the edges have weights associated with them. Update matrix entry to contain the weight. …
