A key (and an associated value) and satisfies the restriction that the key in any node is larger than the keys in all nodes in that node's left subtree and smaller than the keys in all nodes in that node's subtree.Each node contains a key, a value, a left link, a link, and a node count.ever, like any code you write, if you write it you need to test it.creates a dict of None's* and "harvesting" is trivial: url_keys = unique_urls.keys()If you would find an index and count useful, you could do something like this: for idx in range(len(urls)): unique_urls.setdefault(urls[idx],[]).append(idx) ...Example would be if all elements in ascending or descending order. Same applies to delete operation and look operation.All of the keys in the left subtree are less than the key in the root.Hence it will be 0 when they are equal, 1 when the left is larger, and -1 when the is larger. On the other hand if then we apply till we get to giving: . We begin with the AVLNode and gift it with a sense of balance.For example, if we want to delete 7 in the above BST, we can link 5 to its only child 9, and remove the node 7. Find minimum element in the subtree of the node to be removed.
