Binary Tree Preorder Traversal Given a binary tree, return thepreordertraversal of its nodes' values. For example: Given binary tree{1,#,2,3}, 1 \ 2 / 3 return[1,2,3]. Note: Recursive solution is trivial, could you do it iteratively? View Code Binary Tree Inorder Traversal Given a...
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 ...

Supplying the general depth-first traversal algorithm with recursion-specific implementations of the frames, edges, and associated functions, we get an iterative variant of the recursive function we wanted to transform. However, the resulting iterative code will not be as readable and understandable as...
For instance, destructors can be used instead of constructors. Consider, for instance, this alternative definition of + on the natural numbers: X+Y=ifX=0thenYelses(p(X)+Y) Sometimes the recursive calls of the algorithm are not simply on the arguments of the constructors. Consider, for ...
