Rotate a list

Write rotate_right(items, steps). It returns a new list in which every item moved steps places to the right. An item that moves past the end of the list comes back at the start.

For example, rotate_right([1, 2, 3, 4, 5], 2) returns [4, 5, 1, 2, 3].

• steps can be bigger than the length of the list, also very big (up to 1,000,000,000 in either direction). A rotation by the length of the list gives the same list.
• steps can be negative. A negative number moves the items to the left.
• An empty list gives an empty list.
