COSC2430: Programming and Data Structures Homework 4: Shortest Path in Graph 1 Introduction You will create a C++ program to find the shortest path given a source vertex and destination vertex. 2 Input and Output G = ( V, E ) is a directed graph, where n vertices and m edges. G can be represented as an adjacency matrix E, n × n , where n < = 10000. Please see Figure 1 as an example. You will read a sparse matrix E from an input file; There will be ONE matrix entry per line in the input file and each line will have a triplet of numbers i, j, length where 1 i, j n indicate the entry and length denotes the length for a directed edge pointing from vertex i to j . Given a source vertex 1 s n and

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
