The queue now contains just vertex 1 with distance 3. Dequeue vertex 1, and enqueue vertex 0 with distance 4. The queue now contains just vertex 0 with distance 4. Dequeue vertex 0, and don't enqueue any vertices. The queue is now empty. Because the queue is empty, breadth-first search terminates. david phelps sings no more night https://boldinsulation.com
