Given a non-empty binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some ...
问题 给出一个二叉树,找到其中的最大路径和。 路径可以从树中任意一个节点开始和结束。 例如: 给出如下二叉树, 返回 。 初始思路 为了简化分析,我们先假设二叉树中所有节点的值都是正数。通过观察可以发现,一棵二叉树的最大路径,就是其左子树的最大路径加上右子树的最大路径。看起来可以从根节点出发通过深度优先递归来求解: 函数 查找路径 如果是叶子节点,返回叶子节点的值 如果不是叶子节点 左子树路径和 ...
