none_of

Interface

template<typename InputIterator, typename Predicate>
inline SPROUT_CONSTEXPR 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.

Examples

#include <sprout/algorithm/none_of.hpp>
#include <sprout/array.hpp>
#include <sprout/container.hpp>
#include <sprout/functional.hpp>
using namespace sprout;

SPROUT_STATIC_CONSTEXPR auto input = array<int, 10>{{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}};
SPROUT_STATIC_CONSTEXPR auto result = sprout::none_of(begin(input), end(input), bind2nd(greater<>(), 10));
static_assert(result, "none of input is greater than 10.");

Complexity

At most last - first applications of the predicate.

Recursive function invocations in O(logN) (logarithmic) depth.
