Any suggestions on how to improve the performance of the code. Passing tests but otherwise timing out.

return sum([a * b * c for a in range(x, 0, -1) for b in range(y, 0, -1) for c in range (z, 0 , -1)])

Moreover, it's a combinatorics puzzle, not a programming exercise.

The JavaScript translation was created before the test framework supported BigInt in its error messages, and native stringification unfortunately drops the n letter at the end, i.e. (10n + "") === "10". This has been fixed; you can reset the trainer and see correct error messages.

Hi,

The input range should be given in the description.

The arrays in the examples have the letter "n" next to the dimensions which is a notation for BigInt in javascript (it took me 1 hour to figure it out)
So, you should convert your result to BigInt format using the function BigInt(number).
It is a very difficult challenge this one! I do not know the coding way but I am trying to understand it mathematically first and I am struggling a lot.
I hope my answer helps you. In general, the instructions are not so helpful, unfortunately.
Amazing riddle anyway!

actual : 1 , expected : 1
wtf?

You can always update it since you're a contributor ^^

Python tests should be updated to use the new test framework correctly.

It's cool but not 7 kyu... especially if you have not some knowledge in combinatorics.

Yes Harvard, this man right here.

@BitemNet: use 3 opening backticks with the python language name like this:

```python

then put in the content (which will look like it's in a Python editor)
and finally follow this with another line having only 3 closing backticks

yes, it's totally wrong. I'm currently updating the kata...
