Introduction
This is the third article in the Tree Traversals - Online Classes.
I have written many articles about non-linear data structures and their traversals. But the more you dive in you can find many more ways to traverse a tree. Here we try to solve the level order tree traversal for a binary tree and we will also try to figure out other variations of this traversal. This can we precisely extended for a n-ary tree as well.
Defining the problem
Let us consider the above tree, if we follow the blue line from root till end and print all the nodes, we will end up printing the lev...

Purpose of article
This article will take over from where we wrapped up in the last article, It will define the remaining two methods elements() and positions() of the Tree ADT for LinkedBinaryTree. And we will also discuss the Tree traversals and code for the Binary Tree. We will finish...
