For simplicity, assume that the Graph implementation always iterates through the neighbors of a vertex in increasing order.0-1 1-2 1-7 2-0 2-4 3-2 3-4 4-5 4-6 4-7 5-3 5-6 7-8 8-6

**2. **
Repeat question 1 for BFS. Also give the length of the shortest
path (number of edges) from vertex 0 to each other vertex.
