A non-recursive algorithm for the traversal of a binary tree is presented in which the order of traversal is defined by an external data array, allowing any of the six possible orders to be selected without modification to the algorithm itself. The extra storage requirements are three pointer ...
同时,每次取了当前节点,我们进行同样的操作(先压右节点,再压左节点),这样可以保证preorder traversal。 /** * Definition for a binary tree node. * public class TreeNode { * int val; * TreeNode left; * TreeNode right; * TreeNode(int x) { val = x; } * }*/classSolution {publicList<Int...

In this article, we will learn about the non recursive algorithm of tree traversals like algorithm for pre-order, post-order and in-order. Submitted by Prerana Jain, on July 26, 2018 1) Algorithm for PostorderIn this traversal first, traverse the leftmost subtree at the external node then ...

Recently, some researchers have s explored non-bottom-up strategies to build a constituent tree. Dyer et al. [15], [35] proposed a top-down transition-based algorithm and, more recently, Liu and Zhang [37] developed a parser that builds the tree in an in-order traversal, seeking a comp...
