25.2 Non-modifying sequence operations [alg.nonmodifying]

25.2.1 All of [alg.all_of]

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

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

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