rustHow to shift elements in a Rust slice?

Shifting elements in a Rust slice can be done using the rotate_left and rotate_right methods. These methods take a mutable slice and a number of elements to shift as arguments.

Example code

let mut v = [1, 2, 3, 4, 5];
v.rotate_left(2);

Output example

[3, 4, 5, 1, 2]

Code explanation

• let mut v = [1, 2, 3, 4, 5];: This line declares a mutable slice v with 5 elements.
• v.rotate_left(2);: This line shifts the elements in the slice v to the left by 2 positions.
