template<class RandomAccessIterator> void stable_sort(RandomAccessIterator first, RandomAccessIterator last); template<class ExecutionPolicy, class RandomAccessIterator> void stable_sort(ExecutionPolicy&& exec, RandomAccessIterator first, RandomAccessIterator last); template<class RandomAccessIterator, class Compare> void stable_sort(RandomAccessIterator first, RandomAccessIterator last, Compare comp); template<class ExecutionPolicy, class RandomAccessIterator, class Compare> void stable_sort(ExecutionPolicy&& exec, RandomAccessIterator first, RandomAccessIterator last, Compare comp);
Requires: RandomAccessIterator shall satisfy the requirements of ValueSwappable.
The type of *first shall satisfy the requirements of MoveConstructible and of MoveAssignable.
Effects: Sorts the elements in the range [first, last).
Complexity: At most comparisons, where , but only comparisons if there is enough extra memory.
Remarks: Stable.
