Is the a way to compare vector to be equal to part of another vector in C++?

If I have:

A = {"one", "two", "three"}

B = {"one", "two"}

I want to avoid creating a new vector from A. Is there a way to use [A.begin(), A.begin()+1] to compare with B?

There is a version of std::equal that could do:

template< class InputIt1, class InputIt2 >
bool equal( InputIt1 first1, InputIt1 last1,
            InputIt2 first2, InputIt2 last2 );
