.. _sprout-algorithm-any_of_equal: ############################################################################### any_of_equal ############################################################################### Interface ======================================== .. sourcecode:: c++ template inline SPROUT_CONSTEXPR bool any_of_equal(InputIterator first, InputIterator last, T const& value); Returns ======================================== | false if [first,last) is empty or if there is no iterator i in the range [first,last) such that ``*i == value`` is true, and true otherwise. 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::any_of_equal(begin(input), end(input), 1); static_assert(result, "any of input is equal to 1."); Complexity ======================================== | At most ``last - first`` applications of the predicate. | Recursive function invocations in *O(logN)* (logarithmic) depth. Header ======================================== | ``sprout/algorithm/any_of_equal.hpp`` | Convenience header: ``sprout/algorithm.hpp``
