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
