Effects: Finds a subsequence of equal values in a sequence.
Returns: The last iterator i in the range [first1,last1 - (last2 - first2)) such that for every non-negative integer n < (last2 - first2), the following corresponding conditions hold: *(i + n) == *(first2 + n), pred(*(i + n), *(first2 + n)) != false. Returns last1 if [first2,last2) is empty or if no such iterator is found.
Complexity: At most (last2 - first2) * (last1 - first1 - (last2 - first2) + 1) applications of the corresponding predicate.
