As of C++11, you can ask a vector or deque to return unneeded memory to the system by calling member function shrink_to_fit. This requests that the container reduce its capacity to the number of elements in the container. According to the C++ standard, implementations can ignore this request so that they can perform implementation-specific optimizations.
A) minimize_memory
B) shrink_to_fit
