给定一个二叉树 struct TreeLinkNode { TreeLinkNode *left; TreeLinkNode *right; TreeLinkNode *next; } 填充它的每个 next 指针,让这个指针指向其下一个右侧节点.如果找不到下一个右侧节点,则将 next 指针设置为 NULL. 初始状态下,所有 next 指针都被设置为 NULL. 说明: 你只能使用额外常数空间. 使用递归解题也符合要求,本题中递归程序占用的栈空间不算做额外的空间复杂度. 你可以假设它是一个完…

这是“每个节点的右向指针”问题的进阶.如果给定的树可以是任何二叉树,该怎么办?你以前的解决方案仍然有效吗?注意:    你只能使用恒定的空间.例如,给定以下二叉树,         1       /  \      2    3     / \    \    4   5    7调用你的函数后,树应该看起来像这样:         1 -> NULL       /  \      2 -> 3 -> NULL     / \    \    4-> 5 -> 7 -&g…
