Since the depth of a balanced binary search tree is about lg(n), you might not worry about running out of stack space, even when you have a million of elements. But what if the tree is not balanced? Then you are asking for trouble, because in the worst case the height of the tree...
Data Structure Binary Search Tree: Inorder Successor in Binary Search Tree 1 struct node { 2 int val; 3 node *left; 4 node *right; 5 node *parent; 6 node() : val(0), left(NULL), right(NULL) { } 7 node(int v) : val(v), left(NULL), right(NULL) { } ...
We propose an efficient parallel algorithm to number the vertices in inorder on a binary search tree by using Euler tour technique. The proposed algorithm can be implemented in O(log N) time with O(N) processors in CREW PRAM, provided that the number of nodes In the tree is N.Masahiro ...

This traversal method can be especially useful in the case of binary search trees, where it helps output all the node values in ascending order. To learn more about other types of tree travels, read Tree Traversal: Inorder, Preorder, Postorder, and Level-order. Inorder Tree Traversal Without...
Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 思路: easy 算法: 1. public TreeNode buildTree(int[] inorder, int[] postorder) { 2. if (inorder == null || inorder.length == 0 || postorde...
Given a binary search tree and a node in it, find the in-order successor of that node in the BST. Note: If the given node has no in-order successor in the tree, return null. Solution1:Iterative: binary search + prev 屏幕快照 2017-09-09 下午3.49.54.png ...
Given a binary search tree and a node in it, find the in-order successor of that node in the BST. Note: If the given node has no in-order successor in the tree, returnnull. Solution 用中序遍历的方式遍历树,这里这个节点的位置有几种可能性: ...
So, I'm trying to do an inorder traversal of a binary search tree using recursion (doesn't HAVE to be recursion, but it seems the simplest to do. My "SizeOf" method works great, and I can print each node using that, so I know the tree is forming... Can anyone clue me into ...
We only consider unbalanced trees here for the sake of simplicity, but in real-world scenarios efficiency of a binary search tree comes from the balanced nature, where each subtree of the root has roughly the same height. Binary trees can be traversed using three different methods named: inor...
