Problem 3. Give an example of a simple, undirected, weighted graph such that a breadth-first traversal outputs
a search-tree that is not a single source shortest path tree. (That is, BFS is not sufficiently powerful to solve
the shortest-path problem on weighted graphs. This motivates Dijkstras algorithm, which will be discussed in
the near future.)
