      std::back_insert_iteratorOutputIteratorイテレータは（間接参照するかどうかにかかわらず）に割り当てられたときにそれを構成しているため、容器に付加が、コンテナのpush_back()メンバ関数を使用するということです。 std::back_insert_iteratorをインクリメントすると、操作は行われません.
      Original:
      std::back_insert_iterator is an OutputIterator that appends to a container for which it was constructed, using the container's push_back() member function whenever the iterator (whether dereferenced or not) is assigned to. Incrementing the std::back_insert_iterator is a no-op.
