Given a binary tree, you need to compute the length of the diameter of the tree. The diameter of a binary tree is the length of thelongestpath between any two nodes in a tree. This path may or may not pass through the root. Example: Given a binary tree 1 / \ 2 3 / \ 4 5 R...

今天介绍的是LeetCode算法题中Easy级别的第124题(顺位题号是543)。给定二叉树,您需要计算树的直径长度。 二叉树的直径是树中任意两个节点之间最长路径的长度。 此路径可能会也可能不会通过根节点。例: 给出一棵二叉树 1 / \ 2 3 / \ 4 5 返回3,这是路径[4,2,1,3]或[5,2,1,3]的长度。 注意:...
