We can keep the standards of this site high by sticking to a consistent format when we answer competition posts. Here's an example of a good format, but feel free to customise it to your needs:
markdown
# [language name](url-to-language-homepage), NN bytes

languagename
code goes here

[Try it online!](url-to-online-test-suite)

Explanations etc.

My algorithm is
$$f(x)=\sum_{i=1}^{N}\begin{cases}\text{MathJax}=\text{good}\\4\text{ formulas}\end{cases}$$

for values in the range $\text{inline}≤x<\text{formula}$.

It will look like this:

If you use a non-ASCII programming language, consider changing NN bytes into NN [bytes](url-to-codepage-info)
