Binary Tree 非递归遍历模板小结(经典!)
Binary Tree的遍历可分为preorder, inorder, postorder和in-level order四种。前3种可用递归或非递归(基于stack，后进先出)，第4种通常用queue(先进先出)，也可以用stack。注意这里是Binary Tree，不需要是Binary Search Tree。nnpreorder遍历非递归模板： n遍历顺序为根、左、右 n思路： n1. 如果根...

A Binary Search Tree (BST) is recursively defined as a <em>binary</em> <em>tree</em> which has the following properties: The left sub<em>tree</em> of a node contains only nodes with keys less than the node's key. The right sub<em>tree</em> of a node contains only nodes with keys greater than or equal to the node's key. Both the left and right sub<em>tree</em>s must also be <em>binary</em> <em>search</em> <em>tree</em>s. A Complete Binary Tree (CBT) is a <em>tree</em> that is completely filled, with the possible exception of the bottom level, which is filled from left to right. Now given a sequence of distinct non-negative integer keys, a unique BST can be constructed if it is required that the <em>tree</em> must also be a CBT. You are supposed to output the level order traversal sequence of this BST.
