Hi everyone,

I'm trying to test whether two std::vector's intersect.

A straightforward way is to sort them, apply std::set_intersection and 
test whether the result set is non-empty.

However, I don't need the result. Is there some algorithm in boost that 
just _tests_ for intersection, i.e., stops when it has found one common 
element?

Best regards,

Jens
