A set contains 2 N subsets, where N is the number or count of items in the set. Therefore are 2^N possible subsets (if you include the original and empty sets), and there is a direct mapping from the bits in the binary representation of x between 0 and 2^N to the elements in the xth subset of S. The time complexity of above solution is O(n.2 n) where n is the size of the given set.. The idea of a simple recursive solution is that if you have all subsets of an array A already generated as S = subsets(A), and now you want to go to a bigger set B which is the same as A, but has a new element x, i.e. Product of all sorted subsets of size K using elements whose index divide K completely.
