How to Reverse an Array in Rust - Step by Step Examples

How to Reverse an Array in Rust ?

To reverse an array in Rust, you can use the slice method reverse() on mutable slices.

In this example,

We have an array named int_array containing integers.
We call the reverse() method on the mutable slice of int_array to reverse the elements in place.
We print the reversed array to demonstrate the reversal.

fn main() {
    let mut int_array = [1, 2, 3, 4, 5];
    int_array.reverse();
    println!("Reversed Array: {:?}", int_array);
}

Reversed Array: [5, 4, 3, 2, 1]

In this example,

We have an array named str_array containing strings.
We call the reverse() method on the mutable slice of str_array to reverse the elements in place.
We print the reversed array to demonstrate the reversal.

fn main() {
    let mut str_array = ["apple", "banana", "cherry"];
    str_array.reverse();
    println!("Reversed Array: {:?}", str_array);
}

Reversed Array: ["cherry", "banana", "apple"]
