Compares the underlying iterators. Inverse comparisons are applied in order to take into account that the iterator order is reversed.

Parameters

lhs, rhs - iterator adaptors to compare

Return Value

1) lhs.base() == rhs.base()
2) lhs.base() != rhs.base()
3) lhs.base() > rhs.base()
4) lhs.base() >= rhs.base()
5) lhs.base() < rhs.base()
6) lhs.base() <= rhs.base()
