Given a binary tree, determine if it is acomplete binary tree. Definition of a complete binary tree fromWikipedia: In a complete binary tree every level, except possibly the last, is completely filled, and all nodes in the last level are as far left as possible. It can have between 1 a...
int GetDepth(TreeNode *root) {if(root == NULL)return0;returnmax(GetDepth(root->left), GetDepth(root->right)) +1; } bool GetAns(TreeNode *root, int dep) {//只有根节点的情况,不用判空,因为不会递归到那if(dep == depth) {returntrue; }if(dep < depth -1) {if(root->left == ...
力扣leetcode-cn.com/problems/check-completeness-of-a-binary-tree/ 题目要求: 思路:1.利用二叉树节点编号与非空节点的关系来做 思路2:根据完全二叉树的节点分布特点来做。规则在图中 code如下: python class TreeNode: def __init__(self, val=0, left=None, right=None): self.val = val self....
判定方式就是采用层序遍历,对于一个完全二叉树来说,访问每个非空节点之前都不能访问过null。 publicbooleanisCompleteTree(TreeNoderoot){if(root==null)returntrue;Queue<TreeNode>q=newLinkedList<>();q.add(root);booleanflag=false;while(!q.isEmpty()){intsize=q.size();for(intk=0;k<size;k++){Tre...
Definition of a complete binary tree fromWikipedia: In a complete binary tree every level, except possibly the last, is completely filled, and all nodes in the last level are as far left as possible. It can have between 1 and 2h nodes inclusive at the last level h. ...
Wilke's tree algebra formalism for characterizing families of tree languages is based on six operations involving letters, binary trees and binary contexts. In this paper a completeness property of these operations is studied. It is claimed that all functions involving letters, binary trees and ...

The main feature of d-maps is as follows:Lemma 2.13\textsf{GLP}_1 is complete with respect to a scattered space (X, \tau ) if, and only if, for any finite, converse-wellfounded tree T, there exists a \tau -open subspace S of X and a surjective d-map f:(S, \tau ) \right...
By defining a new measure to community structure, exclusive modularity, and based on cavity method of statistical physics, we develop a mathematically principled method to determine the completeness of community structure, which represents whether a partition that is either annotated by experts or given...
