WebThe first thing to do is to fill an array with the values for which the max heap will be created. This is called theArray. Next, a PriorityQueue, theQueue, is created and then the elements from theArray are added to this. This uses the method add (), e.g. theQueue.add (10) to add 10 to the end of the queue. WebTo verify if a given array is a max-heap, we need to check whether each node satisfies the max-heap property, that is, that k e y [ P a r e n t ( i)] ≥ k e y [ i] for all nodes i except for the root. In a max-heap, the parent of node i is stored at the position ( i − 1) / / 2.
