Question: Let G = (V, E) be a directed graph with positive edge lengths. Let s be a vertex in G. Let |E| ? |V |.

Let G = (V, E) be a directed graph with positive edge lengths. Let s be a vertex in G. Let |E| ? |V |. For each u ? V , define best[u] to be the minimum number of edges in a shortest path from s to u. Modify the below Dijkstra's algorithm to give an O(|E|log|V |) algorithm to compute best[u] for all nodes u in V .
