WebbExchanges the values of each of the elements in the range [first1,last1) with those of their respective elements in the range beginning at first2. The function calls swap (unqualified) to exchange the elements. The behavior of this function template is equivalent to: WebbThe returned range is defined by two iterators, one pointing to the first element that is not less than value and another pointing to the first element greater than value. The first iterator may be alternatively obtained with std::lower_bound (), the second - with std::upper_bound () .
