Returns: A pair of iterators i and j such that j == first2 + (i - first1) and i is the first iterator in the range [first1,last1) for which the following corresponding conditions hold:
!(*i == *(first2 + (i - first1))) pred(*i, *(first2 + (i - first1))) == false
Returns the pair last1 and first2 + (last1 - first1) if such an iterator i is not found.
Complexity: At most last1 - first1 applications of the corresponding predicate.
