Quick Sort Algorithm

1. In your Cargo.toml, set the crate name:

[package]
name = "quick_sort_yq"
# ...existing fields...

Now, others can add your crate as a dependency and use quick_sort_yq::quick_sort.

2. Update main.rs to use your library:

use quick_sort_yq::quick_sort;

fn main() {
    let mut arr = [3, 6, 8, 10, 1, 2, 1, 80];
    println!("Before: {:?}", arr);
    quick_sort(&mut arr);
    println!("After:  {:?}", arr);
}
