Assign to this deque the values in the range starting at the specified first and ending immediately before the specified last iterators of the (template parameter) type INPUT_ITERATOR. The (template parameter) type INPUT_ITERATOR shall meet the requirements of an input iterator defined in the C++11 standard [input.iterators]providing access to values of a type convertible to value_type, and value_type must be copy-assignable and emplace-constructible from *i into this deque, where i is a dereferenceable iterator in the range [first .. last)] (see {Requirements on VALUE_TYPE}). The behavior is undefined unless first and last refer to a sequence of valid values where first is at a position at or before last.
