    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");
}

      @maegul@lemmy.ml using sort looks like a nice solution. For very large lists it will be doing more work than is strictly necessary, but for most use cases that would be great, and nice and simple.

        Thanks! Yea I’m clearly taking the easy route there with sort.

        Though it did make wonder why there’s no max or min methods even though there’s a sort … question for another time perhaps 🤔
