i shouldve used reduce. very little difference but this is better

             let (loc, max) = bank[bank_index..bank_len - i]
                 .iter()

-                .fold((0_usize, &0_u64), |(maxi, max), (i, n)| {
-                    if n > max { (i, n) } else { (maxi, max) }
-                });

+                .unwrap();
 
             ((number * 10) + max, bank_index + loc + 1)
