Assign to this object the value resulting from first clearing this vector and then inserting (in order) each `value_type` object in the range starting at the specified `first` element, and ending immediately before the specified `last` element. If an exception is thrown, `*this` is left in a valid but unspecified state. Throw `std::length_error` if `distance(first,last) > max_size()`. The (template parameter) type `INPUT_ITER` shall meet the requirements of an input iterator defined in the C++11 standard [24.2.3] providing access to values of a type convertible to `value_type`, and `value_type` must be `emplace‐constructible` from `*i` into this vector, 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 range of valid values where `first` is at a position at or before `last`.
