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

Let G = (V, E) be a directed graph with positive edge lengths. Let s, t ? V . Assume that |E| ? |V |. Show how to modify Dijkstras algorithm below to derive an O(|E|log|V |) algorithm to decide if there is a unique shortest path from s to t in G. If there is return true, else return false.
