Given a root node reference of a BST and a key, delete the node with the given key in the BST. Return the root node reference (possibly updated) of the BST. Basically, the deletion can be divided into two stages: Search for a node to remove. If the node is found, delete the node...
Can you solve this real interview question? Delete Node in a BST - Given a root node reference of a BST and a key, delete the node with the given key in the BST. Return the root node reference (possibly updated) of the BST. Basically, the deletion can b
Explanation: Given key to delete is 3. So we find the node with value 3 and delete it. One valid answer is [5,4,6,2,null,null,7], shown in the above BST. Please notice that another valid answer is [5,2,6,null,4,null,7] and it's also accepted. 首先对于BST 来说左子树的节...

英文网址:450. Delete Node in a BST。 中文网址:450. 删除二叉搜索树中的节点。 思路分析 求解关键:BST 的删除结点操作在《数据结构与算法》这一类的教科书上都有介绍。 虽然这个操作是计算机科学家 Hibbard 发明的,但其实这个操作非常简单且直观。
力扣leetcode.cn/problems/delete-node-in-a-bst/ 题目 可以有两种答案。 思路 你删除的结点有几种情况,三种吧,拥有左子树和右子树,只有左子树, 只有右子树,那么下面分析这种情况。 1、只有左子树:这种情况直接让左子树接管此点。 2、只有右子树:这种情况直接让右子树接管此点。 3、拥有左子树和右子树,那...
This is an invalid board that you will not receive – as battleships will always have a cell separating between them. Follow up: Could you do it in one-pass, using only O(1) extra memory and without modifying the value of the board? 【解答】要数有多少 battleship,并且要求使...
