naive function array sorting test.rs

fn sort_array(numbers: &[i32]) -> &[i32] {
  let mut sorted_numbers = numbers.clone();
  sorted_numbers.sort();
  sorted_numbers
}

fn main() {
  let numbers: [i32; 7] = [7,1,5,2,4,3,6];
  let sorted_numbers = find_duplicates(&numbers);
  println!("numbers: {:?}", numbers);
  println!("sorted_numbers: {:?}", sorted_numbers);
