.. _sprout-algorithm-find: ############################################################################### find ############################################################################### Interface ======================================== .. sourcecode:: c++ template 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 ======================================== .. sourcecode:: c++ #include #include #include using namespace sprout; SPROUT_STATIC_CONSTEXPR auto input = array{{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. Header ======================================== | ``sprout/algorithm/find.hpp`` | Convenience header: ``sprout/algorithm.hpp``
