std::front_insert_iterator é um iterador de saída que prepends elementos para um recipiente para o qual foi construído, utilizando a função do recipiente membro push_front() sempre que o iterador (se dereferenced ou não) é atribuído. Incrementando a std::front_insert_iterator é um não-op.

Original:

std::front_insert_iterator is an output iterator that prepends elements to a container for which it was constructed, using the container's push_front() member function whenever the iterator (whether dereferenced or not) is assigned to. Incrementing the std::front_insert_iterator is a no-op.
