One of the standard and useful method of finding the power set is through bit-masking.
Consider a number with N-bits in its binary representation, if we consider that the state of i^th bit depicts whether the i^th array element is included in the current subset or not, then we can uniquely identify one of the subsets (as each number has a different binary representation).

While coming back from each recursion call we add the current node in the current recursion call to the last node of the partially reversed Linked List and assign the current node to null.
