旋转是AVL树最重要的操作了,理解了旋转就理解了AVL树的实现原理。 左单旋转 下图节点上面的数字表示平衡因子 如上图所示: 插入13后,右边子树11节点的平衡因子变为了2(左右节点的高度差), 整个avl树开始不平衡,这时便要开始以12为轴心进行一次左单旋转。具体旋转的操作是原来11的父节点10指向12,12的左节点指向11...

用python编写华容道 华容道 leetcode 在这部分内容里,我们用HashTable取代AVLTree以进一步提高系统的检索效率。毕竟我们不需要AVLTree的排序功能。另外,从纯粹的理论上来说,AVLTree的算法复杂度至少是O(Log2(x))级别,而HashTable则接近于O(C)级别。 一、 使用HashTable 在华容道程序中,要搜索以前出现过的布局,及时...

2. AVL Tree The main function performs the following: Initializes an empty AVL tree. Reads values from an input file and adds them to the AVL tree. Prints on the terminal all values of the AVL tree in the breadth-first fashion.

That's pretty hard to beat as it's the cost of a pointer to each object. It's also 66% less overhead than a typical binary tree implementation (e.g. Red-Black Tree, AVL-Tree, AA-Tree, Splay-Tree, Treap, etc.) for which every node must also store two pointers to children nodes...
