WebAlgorithm for implementing Priority Queue using Binary Heap. Step1: Create a function heapify () to heapify the elements in the Binary Tree if any changes are made. Step2: Find the largest among root, left child, and right child, then recursively call the same function until the root element matches the largest element. WebDequeue vertex 5, and don't enqueue any vertices. 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.
