Given two binary trees, write a function to check if they are the same or not. Two binary trees are considered the same if they are structurally identical and the nodes have the same value. Example 1: Input: / \ / \ [,,], [,,] Output: true Example 2:…
1.. 平衡二叉树 平衡二叉树要求,对于任意一个节点,左子树和右子树的高度差不能超过1. 平衡二叉树的高度和节点数量之间的关系也是O(logn) 为二叉树标注节点高度并计算平衡因子 AVL树是一棵平衡二叉树 2.. 实现AVL树的业务逻辑 import java.util.ArrayList; public class AVLTree<K extends Comparable<K>, V> { private class Node { public K key; pub…
