rust冒泡排序

使用rust写的冒泡排序

fn bubble_sort(arr: &mut [u32]) {
    let len = arr.len();
    for i in 0.. len {
        for j in 0.. len - i - 1 {
            if arr[j] > arr[j + 1] {
                arr.swap(j, j+ 1);
            }
        }
    }
}

fn main() {
    let mut arr = [5, 2, 9, 1, 3];
    println!("Before sorting: {:?}", arr);
    
    bubble_sort(&mut arr);
    
    println!("After sorting: {:?}", arr);
}
