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 ...
因为是preorder traversal, 我们需要先print root,然后左节点,最后右节点,而且root左边子树一定比右边子树先print出来,所以,我们可以先把当前root的右节点压栈,然后把root的左节点压栈,这样每次从栈里取的时候,可以保证左边节点的root先取。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...

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 ...
