any_of

Interface

template<typename InputIterator, typename Predicate>
inline SPROUT_CONSTEXPR bool
any_of(InputIterator first, InputIterator 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.

Examples

#include <sprout/algorithm/any_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::any_of(begin(input), end(input), bind2nd(greater<>(), 5));
static_assert(result, "any of input is greater than 5.");

Complexity

At most last - first applications of the predicate.

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