WebExplanation: The above code implements Dijkstra's algorithm to find the shortest path between two points in a maze. The maze is represented as a 2D array where 1s represent paths and 0s represent walls. The algorithm uses a priority queue to select the unvisited cell with the minimum distance from the source cell. WebRun Dijkstra’s algorithm from v 0 to get all distances from v 0 to all vertices in V. Reverse the graph and run Dijkstra’s again from v 0. Observe that the output corresponds to the dis- tances of the path from all other vertices to v 0 in the original graph. For any pair of vertices u, w ∈ V , the shortest distance from u to w using a ...
