Trees are one of the most important data structures in computer science.We’re usually interested in a balanced tree, because of its valuable properties. Their structure allows performing operations like queries
For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. /** * Definition for binary tree * struct TreeNode { * int val; * TreeNode *left; * TreeNode *right; * TreeNode(int x...
For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees ofeverynode never differ by more than 1. 解题思路: 递归即可,JAVA实现如下: 1 2 3 4 5 6 7 8 9 10 11 12 publicbooleanisBalanced(TreeNode root) { if(root==null) ret...
