2. we are given a directed graph G =(V, E) on which each edge (u,v) E E has an associated value r(u,v), which is a real number in the range 0 r(u,v)s 1 that represents the reliability of a communication channel from vertex u to vertex v. We interpret r(u,v) as the probability that the channel from u to v will not fail, and we assume that these probabilities are independent. Explain how one can use Dijkstra's algorithm to find the most reliable path between two given vertices
