The function template std::disjoint<...>(...) testing (in linear time) 
whether two sorted ranges contain no elements in common looks like an 
obvious omission from <algorithm>. The declaration is similar to 
std::includes():
 
template<class InpIt1, class InpIt2, class BinPred> 
   bool disjoint(InpIt1 first1, InpIt1 last1, InpIt2 first2, InpIt2 
last2, BinPred _Comp=less<>);
