Sorting Algorithm in Rust

To implement a sorting algorithm in Rust, you can use the built-in sort method provided by the Vec type. The sort method sorts the elements of a vector in ascending order based on their natural order. Here's an example:

fn main() {
    let mut numbers = vec![5, 2, 8, 1, 9];
    numbers.sort();
    println!("{:?}", numbers);
}

In this example, we create a vector numbers with some unsorted integers. We then call the sort method on the vector, which sorts the elements in ascending order. Finally, we print the sorted vector using println!.

The output of this code will be [1, 2, 5, 8, 9], which is the sorted version of the original vector.

If you want to sort the elements in descending order, you can use the sort_by method and provide a custom comparison function. Here's an example:

fn main() {
    let mut numbers = vec![5, 2, 8, 1, 9];
    numbers.sort_by(|a, b| b.cmp(a));
    println!("{:?}", numbers);
}

In this example, we use the sort_by method and provide a closure that compares two elements in reverse order using the cmp method. This sorts the elements in descending order.

The output of this code will be [9, 8, 5, 2, 1], which is the sorted version of the original vector in descending order.

These examples demonstrate how to use the built-in sorting methods in Rust to sort elements in ascending or descending order. You can apply these methods to any type that implements the Ord trait, which includes most of the built-in types in Rust.
