## Mix Order Traversal of a Binary Tree

Given a Binary Tree consisting of** N** nodes, the task is to print its Mix Order Traversal.

Mix Order Traversal_ is a tree traversal technique, which involves any two of the existing traversal techniques like Inorder, Preorder and Postorder Traversal. Any two of them can be performed or alternate levels of given tree and a mix traversal can be obtained._

Examples:

_Input: _N = 6

_Output: __7 4 5 1 3 6 _

Explanation:

_Inorder-Preorder Mix Traversal is applied to the given tree in the following order: _

_Inorder Traversal is applied at level 0 _

_Preorder Traversal is applied at level 1 _

Inorder Traversal at level 2.

_Output: __4 5 7 1 6 3 _

## Tree Traversal in JavaScript

A tree is a non-linear data structure — a collection of nodes connected by directed (or undirected) edges. Each node contains a **value **andthe connection between nodes is called edges. The top-most node is called root, a node without children is called leaf node. Nodes with same the same parent called siblings. The depth of a node is the number of edges from the root to the node and the height of a node is the number of edges from the node to the deepest leaf.

How can we visit every node in a tree? The common algorithms of traversing a tree are breadth-first search(BFS) and** depth-first search**(DFS).

With BFS we visit nodes level-by-level. We explore the breadth, i.e., full width of the tree at a given level, before going deeper.

BFS example

Usually, we’ll encounter binary tree, so we implement the breadth-first search using binary tree in the following examples.

## What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

## Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

## What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

## JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

``````<script type="text/javascript">
document.write("Hello World!");
</script>
``````

## How to comment JavaScript code?

• For single line comment in JavaScript we have to use // (double slashes)
• For multiple line comments we have to use / * – – * /
``````<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

</script>
``````
