4. Single source shortest path problem: Given a graph G = (V, E) and a source vertex s, find the shortest paths from s to all the other vertices. We use |V| and |E| to denote the number of vertices and number of edges respectively. (a) Describe the algorithm (including the data structure to present the graph). (b) What is the time complexity if a binary heap is used. Binary heap is the heap used in the heap sort. (c) What is the time complexity if a Fibonacci heap is used.
