Text formatting guide

CP hub uses a content editing markup language called CP Hub Flavored Markdown, which is an extension of standard Markdown.

Basic Markdown Syntax

See the Markdown Guide - Basic Syntax for basic Markdown syntax.

We use KaTeX for rendering $\LaTeX$ expressions in Markdown.

To write inline $\LaTeX$ expressions, use double dollar signs for block math and single dollar signs for inline math.

Example: $x = \frac{ -b \pm \sqrt{b^2 - 4ac} }{2a}$

This rendered as: $x = \frac{ -b \pm \sqrt{b^2 - 4ac} }{2a}$

To write block $\LaTeX$ expressions, use math code blocks described below (language identifier is math).

Example:

```math
x = \frac{ -b \pm \sqrt{b^2 - 4ac} }{2a}
```

This rendered as:

x = \frac{ -b \pm \sqrt{b^2 - 4ac} }{2a}

Surrounding double dollar signs ($$) to create block equations is not supported. Will be supported in the future.

To create code blocks, use triple backticks (```) before and after the code. For inline code, use single backticks (`).

Example:

```cpp
#include <bits/stdc++.h>
```

This rendered as:

#include <bits/stdc++.h>

To specify the language for syntax highlighting, add the language identifier right after the opening backticks, like: ```cpp.

CP Hub supports syntax highlighting for the following languages:

CP Hub Flavored Markdown extends standard Markdown with additional features especially interconnectedness between contents within CP hub.
