Given a binary tree, flatten it to a linked list in-place. For example,Given The flattened tree should look like: click to show hints. ...
给定一刻二叉树,将二叉树按照前序遍历的顺序转为单链表,右指针指向next,左指针指向None 分治法:将左 右子树变为单链表,分别返回左右链表的最后一个节点,让左链表的最后一个节点指向右节点的第一个节点,完成合并。右链表的最后一个节点即为整个链表的最后一个节点。 遍历法:二叉树的非递归前序遍历。从栈顶取出节点cur,依次将cur的右节点 左节点压入栈,然cur指向栈顶节点。 ...
