543. Diameter of Binary Tree

Given the root of a binary tree, return the length of the diameter of the tree.

The diameter of a binary tree is the length of the longest path between any two nodes in a tree. This path may or may not pass through the root.

The length of a path between two nodes is represented by the number of edges between them.

解题重点：
1. 经过某个节点路径的长度等于节点左右子树的深度之和减去1
2. 二叉树的直径就是所有节点的路径长度中的最大值
3. 先递归调用左儿子和右儿子求得它们为根的子树的深度 LL 和 RR ，则该节点为根的子树的深度即为max(L,R)+1
4. 节点的长度等于L+R+1
5. 递归搜索每个节点并设一个全局变量 ans记录最大值
