Use the code to implement the dijkstra algorithm in the weighted directed graph

We can implement Dijkstra's Algorithm using C/C++ or Java. First, define a graph that contains an adjacency list for each node, and the distances between nodes. Then, define an array to store the shortest distance from each node to the starting node, and initialize it to infinity. Next, starting from the starting node, check the adjacent nodes of this node, update the shortest path array, if the distance from the current node to the adjacent node is shorter, update the shortest path array. Then, select an unprocessed node closest to the starting node, and repeat the above steps until all nodes are processed. Finally, calculate the shortest distance from the starting node to each node.
