An AVL tree is a self-balancing binary search tree. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property. Figures 1-4 illustrate the rotation rules. Now g...
int getHeight(AVLTree A) { return A == NULL ? -1 : A->height; } // LL旋转 // 把B的右子树腾出来挂上A的左子树,再将A挂在B的右子树上,返回B作为当前子树的根 AVLTree LLRotation(AVLTree A) { // 此时根节点是A AVLTree B = A->left; // B为A的左子树 A->left = B->right; ...

平衡二叉树(AVL Tree)(左旋、右旋) AVL Trees (Balanced binary search trees) 平衡二叉树的定义:左右子树深度差绝对值不能超过1。 是什么意思呢?比如左子树的深度是2,右子树的深度只能是1 或者3。 这个时候我们再按顺序插入1、2、3、4、5、6,一定是这样,不会变成一棵“斜树”。 那它的平衡是怎么做到...

PAT 1066 Root of AVL Tree C++版 1.题意 给出一个整数序列,现在需要让你输出以这个序列构建得到的AVL树的根节点。 2.分析 之前我一直都是按照个人的理解做AVL ,对于考试题来说,则是相当简单的,但是如果让我单独实现一棵AVL树,我之前是不会的。但是今天看到晴神的书之后,恍然大悟,又进一步理解到**“算法...
