Pathological Tree:The Binary Tree has a single child, i.e. either left node or right node. Skewed Binary Tree:It is similar to a pathological tree in which the binary tree is either dominated by left or right nodes. And it has two types: Left Skewed Binary tree and Right Skewed Binary...
We are given therootof a binary tree with unique values, and the valuesxandyof two different nodes in the tree. Returntrueif and only if the nodes corresponding to the valuesxandyare cousins. Example 1: Input: root =[1,2,3,4], x =4, y =3 Output:false Example 2: Input: root =[...
Given a binary tree, return thelevel ordertraversal of its nodes' values. (ie, from left to right, level by level). For example: Given binary tree[3,9,20,null,null,15,7], 3 / \ 9 20 / \ 15 7 return its level order traversal as: [ [3], [9,20], [15,7] ] 最显然分层搜...
Binary tree (a) has 8 nodes, with node 1 as its root. Node 1's left child is node 2; node 1's right child is node 3. Notice that a node doesn't need to have both a left child and right child. In binary tree (a), node 4, for example, has only a right child. Further...
Binary Tree Right Side View 中文网站:199. 二叉树的右视图 问题描述 Given the root of a binary tree, imagine yourself standing on the right side of it, return the values of the nodes you can see ordered from top to bottom. Example 1: Input: root = [1,2,3,null,5,null,4] Output: ...

A binary tree comprises of parent nodes, or leaves, each of which stores data and also links to up to two other child nodes (leaves) which are visualized spatially as below the first node with one placed to the left and with one placed to the right. ...
Binary Tree Preorder Traversal Given a binary tree, return the preorder traversal of its nodes' values. For example: Given binary tree {1,#,2,3}, 1 \ 2 / 3 return [1,2,3]. 栈迭代 复杂度 时间O(b^(h+1)-1) 空间 O(h) 递归栈空间 对于二叉树b=2 ...
Given a binary tree, return the level order traversal of its nodes' values. (ie, from left to right, level by level). For example: Given binary tree [3,9,20,null,null,15,7], 代码语言:javascript 代码运行次数:0 运行 AI代码解释 ...
