In this article, we are going to learn Level order traversal on a binary tree: Inorder, Preorder and Postorder Traversal. Submitted by Radib Kar, on September 29, 2018 For traversal on any binary tree, we mainly use three types of traversal. Those are:Inorder traversal Preorder ...
Binary treeDepth-first traversalNon-recursiveThe recursive algorithms for depth-first traversal of a binary tree are widely expatiated upon in data structure textbooks. There are three depth-first traversal sequences for a binary tree, preorder, inorder, and postorder traversal sequences. My ...

the biggest problem lies in finding the time complexity of finding the predecessor nodes of all the nodes in the binary tree. Intuitively, the complexity is O(nlogn)O(nlogn), because to find the predecessor node for a single node related to the height of the tree. But in fact, finding ...
In-Order Traversal In-order depth first tree traversal is one of the most commonly used traversal orders (particularly in ordered data structures such as binary trees) because they return nodes in order by their value. Hey, Tyler here. I'm currently working on some great web development and ...
data); } } The time complexity for recursive approach is O(n), where n is the number of nodes in the binary tree. This is because each node in the tree is visited exactly once. The space complexity is O(h), where h is the height of the tree. This complexity arises from the use...

But a hierarchical data structure like a tree can be traversed in different ways. Tree traversal Let's think about how we can read the elements of the tree in the image shown above. Starting from top, Left to right 1 -> 12 -> 5 -> 6 -> 9 Starting from bottom, Left to right ...
Given a binary tree, perform vertical traversal on it. In vertical traversal, nodes of a binary tree are printed in vertical order. Assume that the left and right child makes a 45–degree angle with the parent.
