Given a binary tree, flatten it to a linked list in-place. 将二叉树展开成链表 [ ] (D:\dataStructure\Leetcode\114.png) 思路:将根节点与左子树相连,再与右子树相连。递归地在每个节点的左右孩子节点上,分别进行这样的操作。 代码 Copy classSolution(object):defflatte
https://leetcode.com/problems/flatten-binary-tree-to-linked-list/ 题意分析: 给出一个二叉树,将这个二叉树变成一个单链形式。 题目思路: 递归的思想,先将根节点连接左子树,然后再连接右子树。 代码(python): View Code
publicvoidflatten(TreeNoderoot){Stack<TreeNode>toVisit=newStack<>();TreeNodecur=root;TreeNodepre=null;while(cur!=null||!toVisit.isEmpty()){while(cur!=null){toVisit.push(cur);// 添加根节点cur=cur.right;// 递归添加右节点}cur=toVisit.peek();// 已经访问到最右的节点了// 在不存在左节...
也就是6作为5的右孩子,5作为4的右孩子,以此类推。 class Solution { private TreeNode prev = null; public void flatten(TreeNode root) { if (root == null) return; flatten(root.right); flatten(root.left); root.right = prev; root.left = null; prev = root; } }...
Given a binary tree, flatten it to a linked list in-place. For example, given the following tree: 1 / \ 2 5 / \ \ 3 4 6 The flattened tree should look like: 1 \ 2 \ 3 \ 4 \ 5 \ 6 题目大意 给定一个二叉树,原地将它展开为链表。
114. Flatten Binary Tree to Linked List 二叉树展开为链表,给定一个二叉树,原地将它展开为一个单链表。例如,给定二叉树1/\25/\\346将其展开为:1\2\3\4\5\6前序遍历将二叉树展开为单链表之后,单链表中的节点顺序即为二叉树的前序遍历访问各节点的顺序。因此,可以对二
Given a binary tree, flatten it to a linked list in-place. For example, Given 1 / \ 2 5 / \ \ 3 4 6 The flattened tree should look like: 1 \ 2 \ 3 \ 4 \ 5 \ 6 递归法 思路 相当于一次先序遍历, 将先访问的点存储在数组里, 下一个访问的节点为之前访问的点的右子树 ...
The flattened tree should look like: 1 \ 2 \ 3 \ 4 \ 5 \ 6 难度:medium 题目:给定二叉树,原地扁平化。 思路:后序遍历 Runtime: 6 ms, faster than 100.00% of Java online submissions for Flatten Binary Tree to Linked List. Memory Usage: 40 MB, less than 100.00% of Java online submiss...
Can you solve this real interview question? Flatten Binary Tree to Linked List - Given the root of a binary tree, flatten the tree into a "linked list": * The "linked list" should use the same TreeNode class where the right child pointer points to the
Given a binary tree, flatten it to a linked list in-place. For example, Given 代码语言:javascript 代码运行次数:0 运行 AI代码解释 1/\25/\ \346 The flattened tree should look like: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 ...
