Rotate an Array by N Elements

Statement

We’re given an array of integers, nums. Rotate the array by n elements, where n is an integer:

• For positive values of n, perform a right rotation.
• For negative values of n, perform a left rotation.

Make sure we make changes to the original array.

Example

Let’s look at the original array below:

On the original array, we perform a left rotation when n is equal to $-1$. The modified array looks like this:

Similarly, when n is equal to $2$, we perform two right rotations one after the other. The modified array looks like this:
