Please help me formulate a tree-based method restoreHeap() that will traverse through the tree-based heap restoring the heap condition through the entire heap.

Below is my code to toss a random node onto the heap.

Please java experts are needed, Ive been at this for hours. Only implementations I can find are array based unfortunately.

public boolean toss(Element value) { //if the root is empty if (root == null) { //create a new node and call it root root = new Node(value); } else { //otherwise //create a node called new Node Node newNode = new Node(value); //create a node, this being the next open parent Node aParent = openParent(); //the new node parent is the open parent newNode.parent = aParent; //if the parents left child is open if (aParent.leftChild == null) { //designate the left child and insert the new node there aParent.leftChild = newNode; } else { //otherwise //insert the new node as the right child aParent.rightChild = newNode; }//end second else }//end first else return true; }//end toss()

By "heap condition" I mean once "restoreHeap" is called manually in the app after manually tossing a few nodes onto the heap its going to satisfy these conditions

The Heap Condition: States that every node's key is larger than(or equal to) the keys of its children.

Therefore, this restore heap algorithm needs to traverse through the tree in ascending order, and restore every node that I tossed in to their proper place.

Please ask if I am unclear and I have been unable to receive much help on this.

As you can see currently In "toss" "restoreHeap" is called to ensure the node meets the heap condition.

However, this is not the correct application I wish to use.

I must toss "n" number of nodes. Then after I am done tossing. Restore the heap.

Therefore modifications are needed in the restoreHeap method to traverse through the tossed items and put them in their proper place.
