23.5 Non-modifying sequence operations [alg.nonmodifying]

23.5.2 Any of [alg.any_of]

template<class InputIterator, class Predicate> constexpr bool any_of(InputIterator first, InputIterator last, Predicate pred); template<class ExecutionPolicy, class ForwardIterator, class Predicate> bool any_of(ExecutionPolicy&& exec, ForwardIterator first, ForwardIterator last, Predicate pred);
Returns: false if [first, last) is empty or if there is no iterator i in the range [first, last) such that pred(*i) is true, and true otherwise.
Complexity: At most last - first applications of the predicate.
