Let's look at how we can optimize a function to turn a `u64` into an array of `u8`s.

```rust
fn main(num: u72) -> pub [u8; 8] {
fn main(num: u64) -> pub [u8; 8] {
let mut out: [u8; 8] = [0; 8];
for i in 0..8 {
out[i] = (num >> (56 - (i * 8)) as u72 & 0xff) as u8;
out[i] = (num >> (56 - (i * 8)) as u64 & 0xff) as u8;
}
