between any two points is the sum of the weights of all the edges on the path. It is known that there are vertex s and T,dijkstra algorithms in V that can find the lowest weight path of S to T (for example, shortest path). This algorithm can also find the shortest path from a vertex s to any other vertex in a graph. The Dijkstra algorithm is the fastest single source shortest path algorithm, which is not included in the negative right direction graph. Algorithm Step: 1. Initial seasonal s={
