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 ...

1. 中序遍历(In-order Traversal):先访问左子树,然后是根节点,最后访问右子树。这种遍历方式可以按照“左-根-右”的顺序访问所有节点。 2. 前序遍历(Pre-order Traversal):先访问根节点,然后是左子树,最后访问右子树。这种遍历方式可以按照“根-左-右”的顺序访问所有节点。 3. 后序遍历(Post-order Traversal...
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 ...

The binary tree in this case can be constructed using either programmer-defined data types if such a facility exists (for example, SNOBOL4) or defining them by functional composition. Recursive programming is supported by LISP and by the so called higher order languages (see next section). 368...
