25.2 Non-modifying sequence operations [alg.nonmodifying]

25.2.3 None of [alg.none_of]

template <class InputIterator, class Predicate> bool none_of(InputIterator first, InputIterator last, Predicate pred);

Returns: true if [first,last) is empty or if pred(*i) is false for every iterator i in the range [first,last), and false otherwise.

Complexity: At most last - first applications of the predicate.
