Your program should be written in C++, execute correctly on CSE unix environment, and compile using g++ compiler using makefile. Makefile must compile program into executable called graph inspector. Your main.cpp program must take input from file via command line (example: prompt:>graph inspector inputfile) with following structure in input file (you may suppose that input file will be well structured so you do not have to error check input). Each line of input file represents graph. First number in line specifies number of vertices in graph. Then pairs of nodes define edges.
