(20 points) Given a strongly connected directed graph, G = (V, E) with positive edge weights along with a particular node v0 V . You wish to pre-process the graph so that queries of the form "what is the length of the shortest path from s to t that goes through v0" can be answered in constant time for any pair of distinct vertices s and t. The pre-processing should take the same asymptotic run-time as Dijkstra's algorithm. Analyse the runtime and provide a proof of correctness
