Mathematically speaking, long has a fixed length, therefore copying it's contents is constant-time operation. On the other hand, you need to zero-out the rest of the bits in the bitset and that you are not able to do in less-than-linear time with respect to the length of the bit_set. So, In theory you cannot do better than O (n ...
