Please use the dictionary found at http://csns.calstatela.edu/wiki/content/msargent/cs460/africa in your assignment. I will write a checker with this dictionary in mind (though it might work on others as well). I put the info in dictionary form, and I also included a checker function to make sure all the adjacency relationships are reciprocal. Whether or not it includes every single possible African country isn't important for our purposes, the adjacency relationships are.
