28.5 Non-modifying sequence operations [alg.nonmodifying]

28.5.1 All of [alg.all_of]

template <class InputIterator, class Predicate> bool all_of(InputIterator first, InputIterator last, Predicate pred); template <class ExecutionPolicy, class ForwardIterator, class Predicate> bool all_of(ExecutionPolicy&& exec, ForwardIterator first, ForwardIterator 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.
