rust reverse an array
To reverse an array in Rust, you can use the reverse
method provided by the Slice
trait. Here is an example:
fn main() {
let mut arr = [1, 2, 3, 4, 5];
arr.reverse();
println!("{:?}", arr);
}
This code declares an array arr
with values [1, 2, 3, 4, 5]
. The reverse
method is then called on the array, which reverses its elements in place. Finally, the reversed array is printed using println!
.
The output of this code will be [5, 4, 3, 2, 1]
.
