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 ...
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...

This approximation can be implemented by means of a very efficient computational structure, which allows for a relevant area saving with respect to the realization of max∗ in both parallel and recursive forms. The high level architecture view includes two components: one component has to find ...
