Add title of your article:

Title should reflect the content of your article and should be less than 70 characters (ideally)

Following is the overview of the atomic elements of a great note (exact components depends upon your topic):

The basic structure of a post is as follows:

You can format your article using:

• Plain text with editor features
• HTML (shall be avoided when possible)
• Markdown

We present the complete structure first and then, we have walked through each of the components in detail. Once you are done with this, you may go through some of our published articles to get the complete idea.

Basic structure

Following is a guide on the structure of your article (Note: it is not fixed so you can customize it accordingly based on your topic):

<!-- heading -->

// Table of contents is optional
<div class="table_of_contents">
    <div href="#firstheading" class="in_page_link">firstheading</div>
    <div href="#secondheading" class="in_page_link">secondheading</div>
    <div href="#thirdheading" class="in_page_link">thirdheading</div>
    <div href="#fourthheading" class="in_page_link">fourthheading</div>
</div>

<br>

<p id="time">Reading time: <Number> minutes | Coding time: <Number> minutes </p>

<div id="algorithm"></div>

### Pseudocode

### Complexity

* Worst case time complexity: <code class="yellow">**&Theta;(<>)**</code> 
* Average case time complexity: <code class="yellow">**&Theta;(<>)**</code> 
* Best case time complexity: <code class="yellow">**&Theta;(<>)**</code>
* Space complexity: <code class="yellow">**&Theta;(<>)**</code>

### Implementations

For single code use markdown as follows:

    ```cpp
    code ...
    ```

// Note: Multiple codes may be avoided when possible

For multiple tabs for multiple implementations, use HTML as follows:

<ul class="tabs">
  <li class="active" rel="tab1">C</li>
  <li class="" rel="tab2">C++</li>
</ul>

<div class="tab_container">
   <h3 class="d_active tab_drawer_heading" rel="tab1">C</h3>
   <div id="tab1" class="tab_content">
   <pre><code class="language-c">

         <!-- Write the code 
         
              There should not be any empty lines in the code
              Convert all "<" and ">" characters to "&lt;" and "&gt;" respectively
              
              The class "language-c" comes from the guide of highlight.js library
              For Java, it is "language-java";
              for C++, it is "language-cpp" and others
         -->

   </code></pre>
   </div>
   <!-- tab 1 C code -->
   
   <h3 class="d_active tab_drawer_heading" rel="tab2">C++</h3>
   <div id="tab2" class="tab_content">
   <pre><code class="language-ppc">
   
       <!--
       
           This is to demonstrate adding a second code
           
       -->
   </code></pre>
   </div>
   <!-- tab 2 C++ code -->

</div>

### Applications

<!-- Write about applications -->

<!-- Note: Discussion tab will appear only when published -->

Text

Add text is simple as you need not use HTML tags and you should avoid it when possible. The key point is that all text should be written in your own words and should not be same as in external images.

You can search your text in a search engine to verify this.

Code

You can add code in your work as follows:

```language
add code here with formatting
```

Code can be added using HTML tags as well but you may avoid it for better rendering.

Tables

Tables should be avoided and can be replaced by Markdown lists. This is because lists render better than table.

Use this HTML code for table:

<table class="infobox biography vcard" style="table-layout:fixed;white-space:normal;"><tbody><tr><th colspan="3" style="text-align:center;font-size:125%;font-weight:bold;max-width:2px"><div class="fn" style="display:inline"></div></th></tr>

<tr><th class="infobox-header" style="background-color: #b0c4de">Heading 1 </th><th scope="row">Heading 2</th><th scope="row">Heading 3</th></tr>
    
<tr style="min-width:2px"><td style="border:1px solid #c8ccd1" class="role">Topic 1</td><td style="border:1px solid #c8ccd1;" class="role">Topic 2</td><td style="border:1px solid #c8ccd1;" class="role">Topic 3</td></tr>

</tbody></table>

This is how table will look like:

Heading 1	Heading 2	Heading 3
Topic 1	Topic 2	Topic 3

Go through our Markdown guide to get the idea on how to add it.

Mathematical Equations

To add equations, you may use:

• MathJax (a library) is enabled so you may use its format directly
• Create the equations in Microsoft Word and then, take a screenshot of the equation and add it as an image

Add a Question

To do so, use the following format:

<div class="container"style="width:100%;">
<h2>Question</h2>
<h4>the question text</h4>
<h6 id="question_message" class="question_message"></h6>
<section class="questionlist">
<div class="correct_option">option1</div>
<div class="wrong_option">option2</div>
<div class="wrong_option">option3</div>
<div class="wrong_option">option4</div>
</section>
<div class="Answer_explanation">
   Answer explanation goes here. Only works with HTML
</div>
</div>

The question will render as:

Add an Image

Upload image using our upload button:

To do so, use the following format:

<a href="/path/image.jpg" data-lightbox="post title">
   <img width="900px" src="/path/image.jpg" alt="topic of image">
</a>

or

![topic of image (Alt text)](Relative Image URL)

Points to note:

• You need to create your own images. Paint is usually used for simple images. Other alternatives is to create the required design using Microsoft Word or Excel and take a screenshot of the concerned section.
• You need to name your image file to a descriptive name before uploading like "binary-search.jpg".
• Image should have the text "iq.opengenus.org" as a watermark or at a corner. You can do this easily using Microsoft Paint.
• Compress the images using online tool before uploading.
• Images may be avoided if not necessary for the topic, as it improves the page speed significantly.

Add a reference link

Note: All external links in your articles should be placed at the end in a reference section only. Within the article, you may use OpenGenus links.

This shall be use to refer to other OpenGenus articles. The code is as follows:

<a id="referencelink" target="_blank" href="https://iq.opengenus.org/regression-techniques/">
Read about various Regression techniques
</a><br>

It works on posts and pages and renders as follow:

Read about various Regression techniques

You are free to create custom images and videos required to explain the note in a better way.

Key takeaways

<div class="key-takeaways">
<h2>Key Takeaways (2 SUM PROBLEM)</h2>
<ul>
<li>When sum (S) is fixed, if you have know one number (A), then the other number is fixed (S-A).</li>
<li>Given a potential first number, the problem becomes a search problem for the second number.</li>
<li>Search can be done with O(logN) time with Binary Search or O(1) time with Hash Map.</li>
</ul>
</div>
