Question: Given an undirected graph G = (V, E) with positive edge weights and two nodes s, t V , design an efficient algorithm to determine

Given an undirected graph G = (V, E) with positive edge weights and two nodes s, t V , design an efficient algorithm to determine the set of all edges that lie on at least one shortest path from s to t. Describe your algorithm with words (no pseudocode!) and explain why it is correct. You must state and justify the runtime.
