}intmaxDepth(TreeNode* root){returncalDepthRecursion(root); } }; Time complexity : we visit each node exactly once, thus the time complexity is \mathcal{O}(N)O(N), where NN is the number of nodes. Space complexity : in the worst case, the tree is completely unbalanced, e.g. each...
Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 【代码】 【递归】 时间复杂度为O(n) 空间复杂度为O(logn) 【队列】 【栈】 classSolution { public: intmaxDepth(TreeNode *root...

A binary tree'smaximum depthis the number of nodes along the longest path from the root node down to the farthest leaf node. class Solution { public int maxDepth(TreeNode root) { if(root == null) return 0; return 1 + Math.max(maxDepth(root.left),maxDepth(root.right)); ...
AN O(N LOG N) MINIMAL SPANNING TREE ALGORITHM FOR N-POINTS IN THE PLANE A synchronized parallel algorithm for finding maximum flow in a directed flow network is presented. Its depth is O( n 3 ( log n) p), where p ( p ≤ n) is the number of processors used. This problem seems ...
Therefore, after an in-depth evaluation of the elements used in recent studies and the nature of wildfire occurrence, 25 were specified and used in this study to generate reliable and accurate wildfire susceptibility maps. In addition, the separate evaluation of stubble burning, lightning strikes, ...
