When you have a N-dimensional array, you should use N indices if you want to get a value. For this case:
`return matrix[0][0]`

I've implemented it myself and I still think it is a 6 kyu due to it being a very basic task. If you still strugling with permutations, you might find this helpful

The video gives an insight on how the algorithm works and the best part -- it is 19 minutes long and you can stop at any momemt if you seem to catch the idea.

well you can just try yourself to make a solution without numpy and without the determinat() method.
Took me a week, but i enjoyed it.
I´m still trying to make my own code for permutations ;)

Nice Kata

Please don't post code without using Spoiler tag - I've added it for you this time.

Also, don't post your solution in Discourse page - you can discuss it in the Solutions tab that is designed for this purpose.

Just so I stop wasting my time, I use float precision and return i64, are tests in rust precise?
My program is working but tests are failling by 1 or 10-12 for large determinants.

in java it should be matrix[0][0] since matrix is int[][] not int[]

Which villain taught you to transmit a vector not by reference?

It looks like 1 of tests is bygged for Python
I Have any number of rundom tests passed and 1 particular basic test failed
