有一棵二叉树,如下图所示: 其中 # 表示空结点. 先序遍历:A B D E G C F 问题:怎么得到从根结点到任意结点的路径呢? 示例:输入 G,怎么得到从结点 A 到结点 G 的路径呢? 很明显,我们一眼就能看出来路径是 A B E G.如何通过程序得到这条路径就是我们接下来需要做的. 定义二叉树的 链式存储结构 如下: typedef struct BiTNode { char data; struct BiTNode* lchild, * rchild; }BiTNode, * BiT
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 starting node to any node in the tree along the parent-child connections. The path must contain at least one node and doe
