How to Reverse an Array in Rust


How to Reverse an Array in Rust ?

Answer

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



✐ Examples

1 Reverse Array of Integers

In this example,

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

Rust Program

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

Output

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

2 Reverse Array of Strings

In this example,

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

Rust Program

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

Output

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