WebAVL trees work by ensuring that the tree is height balanced after an operation. If we were to have to calculate the height of a tree from any node, we would have to traverse its two subtrees making this impractical. Instead, we store the height balance (or height) information of every subtree in its node.

WebDeletion in AVL Trees: The deletion works in a similar manner. First, we need to find the node to be deleted. Then, we delete the node and if the tree loses balance on removing the need, then we need to rebalance it.
