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)`
