In the above example, we have inserted a new node 20 to the left of the right to node 30. We can see that after inserting a new node the balance factor of node 30 becomes -2 and the tree becomes unbalanced. To make this tree balanced tree we will apply RL Rotation on the tree. ...

AVL tree stands for Adelson, Velskii & Landis Tree, and it can be explained as an extension of the binary search tree data structure. Though it’s similar to a binary search tree, there is one highlight of a difference that is the height of the tree value should be <=1, and unlike ...

平衡二叉树又称平衡二叉排序树(Self-Balancing Binary Tree),也称AVL树,其可以保证较高的查询效率; 平衡二叉树具有以下特点: 其可以是一棵空树,或者左右两棵子树的高度差的绝对值不超过1(即Math.abs(左子树height - 右子树height) <= 1); 左右两棵子树必须都是平衡二叉树; ...
平衡二叉树(Balanced Binary Tree)又被称为AVL树(有别于AVL算法) 在AVL中任何节点的两个儿子子树的高度最大差别为1,所以它也被称为高度平衡树,n个结点的AVL树最大深度约1.44log2n。查找、插入和删除在平均和最坏情况下都是O(logn)。增加和删除可能需要通过一次或多次树旋转来重新平衡这个树。这个方案很好的解...
