def rotate(nums, k):
    """
    Rotate the elements of the list nums to the right by k positions.

    Args:
        nums (List[int]): List of integers to be rotated.
        k (int): Number of positions to rotate the elements.

    Returns:
        None. Modifies nums in-place.

    Example:
        >>> rotate([1,2,3,4,5,6,7], 3)
        [5, 6, 7, 1, 2, 3, 4]
    """
    k %= len(nums)  # Adjust k if it's larger than the length of the list

    # Use slicing to shift the elements to the right
    nums = nums[-k:] + nums[:-k]

    print(nums)  # Print the rotated list (optional)

# Example usages
rotate([1,2,3,4,5,6,7], 3)
rotate([-1,-100,3,99], 2)
rotate([1,2], 3)
