std::vector<bool> behaves similarly to std::vector, but in order to be space efficient, it: Does not necessarily store its elements as a contiguous array. Exposes class std::vector<bool>::reference as a method of accessing individual bits. In particular, objects of this class are return...

reference (or pointer), there will be two copies of the same vector in memory in the program. That is, the function body will have a copy of the vector in memory that is different from the original vector outside the function body. One way to avoid such two copies but still have two...
