In this Example we will discuss is using a priority queue to implement Dijkstra's Algorithm. The basic idea of this method is to keep track of the minimum distance from the source node to each node in the graph. We will also keep track of the previous node in the shortest path from the source node to each node. midas ben white

WebDijkstra algorithm is one of the prominent algorithms to find the shortest path from the source node to a destination node. It uses the greedy approach to find the shortest path. The concept of the Dijkstra algorithm is to find the shortest distance (path) starting from the source point and to ignore the longer distances while doing an update. WebDijkstra's Algorithm. Dijkstra algorithm is a single-source shortest path algorithm. Here, single-source means that only one source is given, and we have to find the shortest path from the source to all the nodes.
