###############################################################################
minmax_element
###############################################################################
Interface
========================================
.. sourcecode:: c++
template<typename ForwardIterator>
inline SPROUT_CONSTEXPR sprout::pair<ForwardIterator, ForwardIterator>
minmax_element(ForwardIterator first, ForwardIterator last);
template<typename ForwardIterator, typename Compare>
inline SPROUT_CONSTEXPR sprout::pair<ForwardIterator, ForwardIterator>
minmax_element(ForwardIterator first, ForwardIterator last, Compare comp);
Returns
========================================
| ``make_pair(first, first)`` if [first,last) is empty, otherwise ``make_pair(m, M)``, where m is the first iterator in [first,last) such that no iterator in the range refers to a smaller element, and where M is the last iterator in [first,last) such that no iterator in the range refers to a larger element.
Examples
========================================
.. sourcecode:: c++
#include <sprout/algorithm/minmax_element.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::minmax_element(begin(input), end(input));
static_assert(*result.first == 1, "a min element is 1.");
static_assert(*result.second == 10, "a max element is 10.");
static_assert(result.first - begin(input) == 0, "a min element position is 0.");
static_assert(result.second - begin(input) == 9, "a max element position is 9.");
Complexity
========================================
| At most ``max(floor((3/2)*(N - 1)), 0)`` applications of the corresponding predicate, where N is ``distance(first, last)``.
| Recursive function invocations in *O(logN)* (logarithmic) depth.
Header
========================================
| ``sprout/algorithm/minmax_element.hpp``
| Convenience header: ``sprout/algorithm.hpp``
