A binary tree isthreadedby making all right child pointers that would normally be null point to the inorder successor of the node (ifit exists), and all left child pointers that would normally be null point to the inorder predecessor of the node. 就是说线索二叉树实际上是把所有原本为空的...

原题网址:https://leetcode.com/problems... Given a non-empty binary search tree and a target value, find k values in the BST that are closest to the target. Note: Given target value is a floating point. You may assume k is always valid, that is: k ≤ total nodes. ...
中序遍历(In-order Traversal)在二叉搜索树(BST)中非常有用,因为它会按照升序的方式访问节点。但在其他类型的树中,这种顺序就不一定了。 示例 下面我会首先解释二叉搜索树的中序遍历,然后用一个图例来说明。 二叉搜索树的中序遍历 在二叉搜索树中,中序遍历会先访问左子树,然后访问根节点,最后访问右子树。由于二...
