More of a logic problem than a coding challenge.

I think it's called numerical sequences in Math.

Array doesn't need any references and Contains is from System.Linq

there are methods Array and Contains

If I understood correctly, a modified list should have been returned.

Very clear explanation, thank you.

Thanks)

It collects the range 0 to n (exclusive) in its return type, a Vec<u32>.

Here's a more explicit example:

return (0..n as u32).collect::<Vec<u32>>();

Does that answer your question?

Please explain how it works

What's the runtime of this?

That's a fair criticism. I think your fork is better.

This mutates inputs, which is not a Best Practice.
