Degenerate Binary Tree 5. Skewed Binary Tree A skewed binary tree is a pathological/degenerate tree in which the tree is either dominated by the left nodes or the right nodes. Thus, there are two types of skewed binary tree: left-skewed binary tree and right-skewed binary tree. Skewed Bi...
# Checking if a binary tree is a complete binary tree in Python class Node: def __init__(self, item): self.item = item self.left = None self.right = None # Count the number of nodes def count_nodes(root): if root is None: return 0 return (1 + count_nodes(root.left) + coun...
Given the root of a binary tree, return the inorder traversal of its nodes' values. 示例: 1 2 Input: root = [1,null,2,3] Output: [1,3,2] 本题就是一个简单的中序遍历二叉树 1#Definition for a binary tree node.2#class TreeNode:3#def __init__(self, val=0, left=None, right...

Given a binary tree, return the postorder traversal of its nodes’ values. 解法 这道题是二叉树后序遍历的非递归实现 先观察递归实现 /** * Definition for binary tree * struct TreeNode { * int val; * TreeNode *left; * TreeNode *right; * TreeNode(int x) : val(x), left(NULL), ri...
A binary tree is used for searching, by placing data in the nodes in such a way that for every node in the tree, all the nodes in its left subtree are less than the parent node's value and all the nodes in its right are greater than the parent node's value. The chapter explains...

A Balanced Binary Tree is a type of binary search tree where the height of the tree is proportional to log base 2 of the number of elements it contains. This balanced structure ensures efficient searching, with elements being found by inspecting at most a few nodes. ...
