In avl tree the balancing factor is checked

WebOct 31, 2024 · By ensuring this balance factor is always equal to 1, AVL trees provide fast and efficient data access and modification operations. In an AVL tree, nodes are inserted in the same way as a regular BST, but the balance factor is checked after each insertion to ensure that the tree remains balanced. Read-only operations of an AVL tree involve carrying out the same actions as would be carried out on an unbalanced binary search tree, but modifications have to observe and restore the height balance of the sub-trees. Searching for a specific key in an AVL tree can be done the same way as that of any balanced or unbalanced binary search tree. In order for search to work effectively it has to employ a compari…
