Answer 1

A vector is just an unordered collection of objects. There is not really anyway to do what you are asking unless you start sorting your vector in specific ways (e.g. if it is sorted you can jump to the middle of the vector and potentially split your search time in half)

You may be better off picking a different data structure (either instead of the vector or in combination with it)
