Fixed

I never knew there was a min function on iter, so short and clever

I forgot about iterators on the array. I need to stop thinking of Rust arrays as C style arrays. I converted my array to a vec first but essentially my solution was the same.

I like this solution alot, I thought some thing like this was possible, but my Rust-foo is not strong enough and I have a hard time navigating the documentation to dig up the idiomatic Rust examples

Well, the random_tests actually sometimes include input that is <= 2!
Thus the statement N will be greater than 2 is incorrect!

E.g. this code in Rust:

fn angle(n: u32) -> u32 {
    assert!(n > 2, "invalid input: n must be bigger than 2");
    // ...
}

sometimes does not pass the random_tests and says:

 Test Failed
invalid input: n must be bigger than 2

See my other solution, it is better
