Question
1. Consider the following weighted graph.

[Graph Description]
- Vertices: A, B, C, D, E, F, G.
- Edges and Weights:
  - A to B: 15
  - A to D: 5
  - B to D: 5
  - C to D: 10
  - C to A: 20
  - D to E: 30
  - E to F: 5
  - F to G: 15
  - G to E: 5

(a) **Apply Dijkstra’s Algorithm** to the graph with A as the source/root and draw the graph for EACH step of the algorithm (include the initial state!).

(b) **Draw the minimum distance spanning tree** associated with the algorithm with A as the root. Label the vertices!

(c) **Suppose a new graph is formed by deleting the edge between D and E.** Run Dijkstra’s Algorithm on this new graph with A as the source/root. You only need to provide the final graph produced by the algorithm.

(d) **Explain how you know the graph from the previous question is disconnected** using only the output of Dijkstra’s Algorithm.
