| void swap( deque& other ); | ||
Exchanges the contents of the container with those of other. 
All iterators and references remain valid. The past-the-end iterator is invalidated.
The behavior is undefined if get_allocator() != other.get_allocator() and std::allocator_traits<allocator_type>::propagate_on_container_swap::value != true.
