_ForwardIterator1  __last1,
_ForwardIterator2  __first2,
_ForwardIterator2  __last2,
_BinaryPredicate  __comp 
) [inline]

Find last matching subsequence in a sequence using a predicate.

Parameters:
first1 Start of range to search.
last1 End of range to search.
first2 Start of sequence to match.
last2 End of sequence to match.
comp The predicate to use.
Returns:
The last iterator i in the range [first1,last1-(last2-first2)) such that predicate(*(i+N), (first2+N)) is true for each N in the range [0,last2-first2), or last1 if no such iterator exists.
Searches the range [first1,last1) for a sub-sequence that compares equal value-by-value with the sequence given by [first2,last2) using comp as a predicate and returns an iterator to the first element of the sub-sequence, or last1 if the sub-sequence is not found. The sub-sequence will be the last such subsequence contained in [first,last1).

Because the sub-sequence must lie completely within the range [first1,last1) it must start at a position less than last1-(last2-first2) where last2-first2 is the length of the sub-sequence. This means that the returned iterator i will be in the range [first1,last1-(last2-first2))
