The document outlines a requirement to modify an unordered linked list by adding a member function for rotating the list to the right in a circular manner. For instance, rotating the list containing elements a to h by 3 positions will result in d e f g a b. It specifies that the list must not be empty and the rotation factor should be valid.

1. 4. Modify the unorderedLinkedList by adding a member function that takes an integer value to
rotate the list to the right in a circular fashion. For example, if the list L contains a b c d e f g h
and you call the member function as in L. rotate ( 3 ) ; The list content will then be rotated by 3
positions to d e f g a b The list should not be empty and the rotation factor is valid.
