find

Interface

template<typename InputIterator, typename T>
inline SPROUT_CONSTEXPR InputIterator
find(InputIterator first, InputIterator last, T const& value);

Returns

The first iterator i in the range [first,last) for which the following corresponding conditions hold: *i == value.

Returns last if no such iterator is found.

Examples

#include <sprout/algorithm/find.hpp>
#include <sprout/array.hpp>
#include <sprout/container.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::find(begin(input), end(input), 8);
static_assert(result != end(input), "found a element equal to 8 from input.");
static_assert(result - begin(input1) == 7, "a found position is 7.");

Complexity

At most last - first applications of the predicate.

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