rustHow to swap elements in a Rust slice?

Swapping elements in a Rust slice can be done using the swap method. This method takes two indices as arguments and swaps the elements at those indices.

Example

let mut v = [1, 2, 3, 4];
v.swap(0, 3);

Output example

[4, 2, 3, 1]

Code explanation

• let mut v = [1, 2, 3, 4];: Declares a mutable slice v with elements 1, 2, 3, and 4.
• v.swap(0, 3);: Calls the swap method on v with arguments 0 and 3, which swaps the elements at indices 0 and 3.
