Super clean and readable!

on behalf of everyone, thank you!

Thanks for correcting the test cases. I was wondering what on earth happened with my calculations!

I had to view the solutions to understand part of this so I need to work on my calculus

I've taken the liberty to fix the open issues and suggestions. A JS translation was added in the process. Enjoy :)

The last two sample tests need to be changed :

n_vals = [[1, 0], [2, 3], [3, 18], [4, 60], [5, 150], [342, **420115062**], [56753, **386209565**]]

The description should use katex to increase readability:

Let `$f(n) = \int_0^n\,\lfloor x\rfloor\:x\:\lceil x\rceil\; dx$`

=>

Let $ f(n) = \int_0^n\,\lfloor x\rfloor\:x\:\lceil x\rceil\; dx$

Link: https://docs.codewars.com/references/markdown/extensions#math-typesetting

f(n) = ∫₀ⁿ ⌊x⌋x⌈x⌉ dx

`$ f(n)=\int_0^n \lfloor x \rfloor x \lceil x \rceil dx $`

$ f(n)=\int_0^n \lfloor x \rfloor x \lceil x \rceil dx $

Example tests are still wrong.

Please see Docs, on Math MarkDown. Duh Innernet at large has even more documentation on that. It might be called Katex.

no you're good reference solution was just wrong :P
