#
Effects: Finds a subsequence of equal values in a sequence.
2
#
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.
