Extra Credit: A bipartite graph is one in which the nodes of the graph can be divided into two sets, A and B, such that there are no edges going within nodes in the same group. Bipartite graphs are commonly used to represent relationships between two different types of objects: e.g., you could use such a graph to represent purchasing relationships between consumers and products (there are no edges within the same group, because consumers don't purchase other consumers, and products don't purchase other products). Create an efficient algorithm to determine whether a connected graph is a bipartite graph.
