Average of Levels in Binary Tree Given a non-empty binary tree, return the average value of the nodes on each level in the form of an array. Example 1: Input: 3 / \ 9 20 / \ 15 7 Output: [3, 14.5, 11] **Explanation:** The average value of nodes on level 0 is 3, on ...
Given a non-empty binary tree, return the average value of the nodes on each level in the form of an array. Example 1: Input:3 / \ 9 20 / \ 15 7Output:[3, 14.5, 11]Explanation: Note: The range of node’s value is in the range of 32-bit signed integer. ...

tree: A model in which entities are arranged into hierarchies of parents and children. triad significance profile: Distribution in the occurrences of various triad motifs in a network [37]. The triad significance profile is one way to characterize the local-level properties of a large network. ...
Average of Levels in Binary Tree [思路]:获得树每一层的平均值,使用广度优先搜索。 那么使用方法: 广度优先 deque vector<double>averageOfLevels(TreeNode*root){vector<double>res;deque<TreeNode*>q;q.push_back(root);while(!q.empty()){doubletemp=0;ints=q.size();for(inti=0;ileft)q.push_...
This Triangulation method surpasses alternative localization algorithms, wherein anchor nodes gauge RSSI levels from neighboring nodes, and DTN employs RSSI data to estimate the proximity of neighboring nodes and form DT triangles. Mani et al. [25] proposed an iterative bounding box approach that was...
