STL: includes

includes

Tests whether one sorted range contains all the elements contained in a second sorted range, where the ordering or equivalence criterion between elements may be specified by a binary predicate.

template<class InputIterator1, class InputIterator2> 
   bool includes( 
      InputIterator1 _First1,  
      InputIterator1 _Last1, 
      InputIterator2 _First2,  
      InputIterator2 _Last1 
   ); 
template<class InputIterator1, class InputIterator2, class BinaryPredicate> 
   bool includes( 
      InputIterator1 _First1,  
      InputIterator1 _Last1, 
      InputIterator2 _First2,  
      InputIterator2 _Last1,
      BinaryPredicate _Comp 
   );
