Dijkstra Application Range:The weights of each edge in the graph are not negative.The shortest path is widely used in the real world, such as finding the shortest path on a map, and this algor
The Dijkstra algorithm solves the single-source Shortest path problem with weighted graphs, which requires that all sides have a non-negative weight . The time complexity of the algorithm is O (N2), which

But every time our staff put demonstrating clothes from the store back to the game, it was very tiring! So now they want to find the shortest ro
length of dis[u]+e[u][v]. If this value is smaller than the value currently known as Dis[v], we can replace the value in the current Dis[v] with the new value. Repeat the 3rd step, if the set Q is empty, the algorithm ends. The value in the final dis array is the shortest
