4. AVL Tree Deletion(340) 5. AVL Tree Insertion(239) AVL Tree Insertion Overview AVL tree is a special binary search tree, by definition, any node, its left tree height and right tree height difference is not more than 1. The purpose of AVL tree is to try best to reduce the search...

While inserting an element in the AVL tree, we need to find the location particular element that needs to be inserted. Then the element is attached the same as an insertion in BST, but after that, it is checked if the tree is still balanced or not, i.e. balance factor of a node is...
After deletion, retrace the path back up the tree (parent of the replacement) to the root, adjusting the balance factors as needed. 下面先来分析下不平衡发生的四种情况: 1、An insertion into the left subtree of the left child of A; (LL) 2、An insertion into the right subtree of the lef...

AVL Tree Rotations In AVL tree, after performing operations like insertion and deletion we need to check thebalance factorof every node in the tree. If every node satisfies the balance factor condition then we conclude the operation otherwise we must make it balanced. Whenever the tree becomes ...
