Consider the following weighted graph:
a. Order of adding the edges: {c, d}, {d, f}, {b, c}, {b, e}, {f, g}, {a, e}, {a, g}
or {c, d}, {d, f}, {b, c}, {f, g}, {b, e}, {a, e}, {a, g}
b. Order of adding the edges: {a, e}, {b, e}, {b, c}, {c, d}, {d, f}, {f, g}
c. Dijkstra’s algorithm shows that the shortest path from a to d has length 15. Because
D(d) = c, D(c) = e, and D(e) = a, we can work backward to find that the path is a, e, c, d.
