PAT甲级1123. Is It a Complete AVL Tree 题意: 在AVL树中,任何节点的两个子树的高度最多有一个;如果在任何时候它们不同于一个,则重新平衡来恢复此属性.图1-4说明了旋转规则. 现在给出一系列插入, 您应该输出生成的AVL树的级别遍历序列,并告知它是否是完整的二叉树. 输入规格: 每个输入文件包含一个测试用例.对于每种情况,第一行包含正整数N(<= 20). 一行中的所有数字都以空格分隔. 输出规格: 对于每个测试用例,将键逐个插入到初始空的AVL树中.然后首先…

1123 Is It a Complete AVL Tree(30 分) 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 rest…

题目:https://pintia.cn/problem-sets/994805342720868352/problems/994805351302414336 题意: 给定n个树,依次插入一棵AVL树,按照层序遍历输出,最后判断这棵AVL树是不是完全二叉树. 思路: 这道题过段时间还要再来手搓一发.AVL模板要记住. 判断是不是完全二叉树的话只用看,如果有一个节点儿子是空,而他之后又出现了至少有一个儿子的节点的话,就不是完全二叉树.[蛮巧妙的] #include<cstdio> #inclu…
