## There can be 4 possible cases that needs to be handled.

The remove method for the AVL tree remove in Java: I have high lighted the re-balance calls / ====================================================== This is the SAME remove method as BST tree, but with rebalance calls inserted after a deletion to rebalance the BST. Deletion in AVL Tree. Deleting a node from an AVL tree is similar to that in a binary search tree. Deletion may disturb the balance factor of an AVL tree and therefore the tree needs to be rebalanced in order to maintain the AVLness.

For this purpose, we need to perform rotations. The two types of rotations are L rotation and R rotation. AVL Tree program in Java. Just like the Red-Black Tree, the AVL tree is another self-balancing BST (Binary Search Tree) in Java.

In the AVL tree, the difference between heights of the right and left subtree doesn't exceed one for all nodes. It takes O (h) time to perform the search, max, min, insert, and delete BST.

### Step 3 - Get the balance factor.

# AVL tree implementation in Python import sys # Create a tree node class TreeNode(object): def __init__(self, key): stumplopping.bar = key stumplopping.bar = None stumplopping.bar = None stumplopping.bar = 1 class AVLTree(object): # Function to insert a node def insert_node(self, root, key): # Find the correct location and insert the node if not root: return TreeNode(key) elif key. Jul 07, AVL tree is a self-balancing Binary Search Tree (BST) where the difference between heights of left and right subtrees cannot be more than one for all nodes.

An Example Tree that is an AVL Tree The above tree is AVL because differences between heights of left and right subtrees for every node is less than or equal to 1.
