Hey again …

THinking about 2-move-semantics/03.rs (around 35 mins). I didn’t think of your solution (just adding mut to the argument of append_to_string! I didn’t know you could do that! Certainly quick and elegant!

I couldn’t help but wonder though that if you wanted the argument you’d have to change a few more things about the place, essentially making the variable mutable from its initialisation and adding reference types down the line … certainly a bit more work. Unless I’m missing something?

Any best-practice style thoughts on simply making a moved variable mutable in a new scope rather than borrowing it?

Heya Andy!

Thoughts on using or not using .sort() in exercise 1-basic-syntax/03.rs rather than rolling your own code for determining minimum and maximum values??

For me, I just (lazily) landed on:

fn main() {
    let mut input = [23, 82, 16, 45, 21, 94, 12, 34];

    // TODO
    input.sort();
    let (smallest, largest) = (input[0], input[input.len()-1]);

    println!("{largest} is largest and {smallest} is smallest");
}
