AVL树(AVL tree)是前苏联计算机科学家Adelson-Velsky和Landis发明的一种自平衡二叉查找树(self-balancing binary search tree)。它有两大属性,一个是继承自二叉查找树的查找属性(binary search property),另一个是AVL树特有的平衡因子属性(balance factor property)。 节点的平衡因子是节点两个子树的高度差BalanceFacto...
这些debug代码对于学习AVL树有帮助作用,如果你有兴趣可以自己运行查看结果。 插入和删除都会影响树的平衡性,因此对于发生变动的节点,需要更新其高度,以便检测平衡性并进行旋转。AVL树的删除挺难想的,需要在草稿纸上比划半天才能想明白。 请看代码。 1//My implementation for avl tree.2#include <iostream>3#include...
There are be different versions of AVL trees. You should implement the one specified on the slides (e.g., when you delete a node with two children, swap the value with the largest value on the left). You should start your program by initializing an empty AVL tree. Your program takes o...
(a) Search a given word. Both the AVL tree and the 2-5 tree should be searched to find the word. The program should print out “[word] found”, along with the count of the word, once for each data structure. If the word is not found the program should output “[word] not found...

旋转是一种用于维护树平衡的操作,常见于AVL树和红黑树等平衡二叉搜索树中。 TreeNode* rightRotate(TreeNode* y) { TreeNode* x = y->left; TreeNode* T2 = x->right; x->right = y; y->left = T2; return x; } 在这个例子中,rightRotate函数执行一次右旋转。右旋转是将节点y下降并将其左子节...
AVL Treeis one such self-balancing tree, which features two different types of rotation (single or double), each with two variants (left or right).Red-Black treesare another, which has 14 different rotations, making it less suitable for implementation in a Homework project. ...
Replace O(n) linked lists with fast O(log n) AVL trees (Cavl library is distributed with libcanard). Traversing the list of RX subscriptions now requires recursive traversal of the tree. Manual DSDL serialization helpers removed; use Nunavut instead. Replace bitwise CRC computation with much fa...

6.2 C/C++实现(C/C++ Implementation) 以下是一个基本的二叉查找树(Binary Search Tree, BST)的C++实现示例。BST是树形查找中常用的一种数据结构。 #include <iostream>struct TreeNode {int value;TreeNode* left;TreeNode* right;TreeNode(int x) : value(x), left(NULL), right(NULL) {}};class BST ...
