      iterator remove_copy( iterator start, iterator end, iterator result, const TYPE& val );
The remove_copy() algorithm copies the range [start,end) to result but omits any elements that are equal to val. remove_copy() returns an iterator to the end of the new range, and runs in linear time. Related topics: copy remove remove_copy_if remove_if
