fn split_string_at(s: String, n: usize) -> (String, String) {

let mut str = String::from(s.clone());

let str_result = str.split_off(n);

return (str, str_result);

}

fn split_slice_at(s: &str, n: usize) -> (&str, &str) {

let (a, b) = s.split_at(n);

return (a, b);

}

// Rust не позволява да имаме две препратки към един и същи mut str едновременно,

// затова това не би сработило

// fn split_slice_mut_at(s: &mut str, n: usize) -> (&mut str, &mut str) {}
