Binary Tree Preorder Traversal | Javascript Solution
Binary Tree Preorder Traversal is an example of tree problems. In this post we will see how we can solve in Javascript.
Problem Description
Given a binary tree, return the preorder traversal 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?
Implementation: Please check the main.js snippet for the solution. If you have different approach in mind or have any suggestion for this implementation feel free to share in the comment below. Thanks!
