The symmetric difference of sets A and B is defined as the set consisting of the elements contained in A, but not in B, and in B, but not in A.

The symmetric difference of sets A and B is defined as the set consisting of the elements contained in A, but not in B, and in B, but not in A. Implement operation SYMMETRIC_DIFFERENCE for sorted singly-linked list representation of sets. Do not use other SET ADT operations, directly operate on linked lists. Give the order of magnitude of the running time of your implementation when it is applied to sets of size m, n.
