AVL树插入的时候为了保证树的平衡会进行旋转,所以根节点不是固定的,每次插入的时候都需要更新根节点,所以插入的核心代码是add函数,我们看到他使用的是递归的实现方式,递归在这里非常重要,他最后一行的balanceTree函数是对树进行调整,也就是说他是自下往上的一直到根节点,只要遇到不平衡的节点都...

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 one line as input. The input line contains n “modification moves” separated by spaces (1 ≤ n ≤ 100). ...

2AVLTreeNode类: ○AVLTreeNode结构体定义了AVL树中每个节点的结构,用struct定义是为了方便在树类访问。 ○_parent指针:指向父节点,用于在旋转等操作中快速定位父节点(记住这里的旋转,这将是后面的重点)。 ○_left和_right指针:分别指向左孩子和右孩子,是二叉树结构的基础。
【百度百科】平衡二叉树(Balanced Binary Tree)具有以下性质:它是一棵空树或它的左右两个子树的高度差的绝对值不超过1,并且左右两个子树都是一棵平衡二叉树。平衡二叉树的常用实现方法有红黑树、AVL、替罪羊树、Treap、伸展树...
(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...
5,Java的的的中TreeMap中的中的实现; (八)总结 AVL树适合用于插入与删除次数比较少,但查找多的情况;相对于要求严格的AVL树来说,红黑树的旋转次数少,所以对于搜索、插入、删除操作较多的情况下,我们就用红黑树。 红黑树广泛应用于C++的STL中,e.g. set、multiset、map、multimap;另外,Java的TreeMap和TreeSet也是...
