excellent!

this allocation works, but your code tries to write beyond it

this would be plenty to know what's going on: *** Error in './test': munmap_chunk(): invalid pointer: 0x00007fff4ec8c690 ***

you need to return an integer array. in C this means the function author (you) needs to dynamically allocate memory for the array. the caller of the function (me) will free the memory.

the numbers are so large you don't have time to simply iterate through them completely => you need a different approach

Could you elaborate what is misleading to you?

Agree. I got it but was confused when I saw that the logic of the best practices solution is completely different than mine.

Reset doesn't affect random tests.
Lightened performance tests more. Good now?

Have you clicked reset?

Thanks @steffan153. :)

Try again, it should be fixed now.

Read one of the posts below stating it doesn't work in Python for the time being.

you had me at warp transmitter XD

My colleague and I were discussing ludicrous programming the other day and he told me that his former employer paid his programmers by line per code. We both agreed, how very stupid this type of payment method is. But we thought it could be some minutes of fun to create such an example of a ridiculous, overcomplicated multi-line code which does the same as a simple one-liner. So please don't take it too serious, this is just a result of a funny afternoon! :)
