Question
Can someone please explain it to me ASAP?!!! This is dijkstra’s shortest path
### Dijkstra's Shortest Path Algorithm **Level 1** **Instructions:** Dijkstra's shortest path algorithm is run on the graph, starting at vertex E. **Graph Explanation:** - The graph consists of 5 vertices labeled A, B, C, D, and E. - The edges between the vertices have weights: - E to A: Weight 6 - E to D: Weight 9 - A to B: Weight 8 - A to D: Weight 9 - B to C: Weight 5 - C to D: Weight 6 - B to A: Weight 2 (This creates a bidirectional connection between A and B with weights 8 in one direction and 2 in the other.) **Question:** Upon completion, what is each vertex's predecessor? **Answer Choices:** For each vertex listed below, select its predecessor: - **A:** - Pick - **B:** - Pick - **C:** - Pick - **D:** - Pick - **E:** - Pick This exercise is about understanding how Dijkstra's algorithm works and predicting the shortest path from vertex E to all other vertices. Please select the correct predecessor for each vertex after running the algorithm.
