The recursion splits the problem into two halves at each level, and there are h levels in the binary tree. Therefore, the time complexity is O(n * h). 4.1.3 High Efficiency Indices as parameters The time complexity of constructing the binary tree using this method is O(n). The main ...

105. Construct Binary Tree from Preorder and Inorder Traversal,这道题用指针,分治思想,相信看代码就能很容易弄懂了这里有一个问题未解决(希望有人可以回答一下:buildTree函数如果不加if语句在input为两个空vector对象的时候报错,搞不清楚为什么,因为我的build函
TreeNode* buildTree(vector<int>& inorder, vector<int>& postorder) { int index = postorder.size() - 1; int l = 0, r = inorder.size() - 1; return buildTreeRecur(index, l, r, inorder, postorder); } //do a level order traversal void levelOrder(TreeNode* root) { ...
Quad-Tree format: You don't need to read this section for solving the problem. This is only if you want to understand the output format here. The output represents the serialized format of a Quad-Tree using level order traversal, wherenullsignifies a path terminator where no node exists bel...
