problem should be done in C++

read in the adjacency matrix for a graph (with 5 vertices) from a file, "adjacency.txt".  An example file is here:  adjacency.txt

This example file contains the following matrix:

1 2 4 1 0
2 0 1 1 3
4 1 2 1 0
1 1 1 0 1
0 3 0 1 3

Store the information in a 2D array.
to return the degree of a vertex in a generic graph.

For example, the following : 

cout << "vertex 3's degree:  " << vertexDegree(G,3) << endl;
cout << "vertex 4's degree:  " << vertexDegree(G,4) << endl;

should output:

vertex 3's degree: 4
vertex 4's degree: 10

thanks!

Suppose you have 4 factors to investigate. You have resource to do 2 replicates of a 2^4 design. But you can only conduct 8 runs every day.

Suppose you have 4 factors to investigate. You have resource to do 2 replicates of a 2^4 design. But you can only conduct 8 runs every day. How would you set up the treatments for each day? What will be the degree of freedom for MSE in your ANOVA table?
