Question
• when printing the tree representation of the priority queue, the maximum element is the root of the tree • for consistency, you should adapt the remove( ) method to remove the maximum element i.e. build a max priority queue • the shape of the tree output should not be skewed 1. public boolean add( PriorityQueueNode x ) This function adds a new node x to the priority queue. The node is added to the heap by comparison of the rating attribute. It involves the "percolate up" process and returns true when finished. 2 public PriorityQueueNode remove( ) This function removes the minimum element of the priority queue and returns it. It involves a call to percolateDown ( int hole ). 3. private void percolateDown( int hole ) This function takes the position of the next available hole in the priority queue and uses it to bubble the elements through the heap until the heap property is restored.
