Write a pthread program to determine the vertex or vetices with the maximum degree. Your program should use concurrency to sum each row of the given adjacency matrix, and then calculate the degree for each vertex. Find the vertex or vertices with the maximum. You should only use concurrency to find the degrees of each of the vertices. The rest should of the program should be done sequentially. Input: From the command line the user will provide file (named: graph.txt ). This file will be only the upper triangle of the adjacency matrix. For example: ./a.out graph.txt In this case, the numbers will be read into from the file graph.txt. Note that this file may contain a total number of integers that is not a multiple of k. Example contents of graph.txt 8 1 0 1 0 1 0 1 1 1 0 0 1 0 0 1 1 1 0 0 1 1 0 0 1 0 0 1 1 Output: To the console (cout) Simply output on each line the degree of each vertex, and then output the vertex or vertices of maximum degree. d(0) = Name your program 0.cpp
