explicit set(const Compare& comp, const Allocator& = Allocator());
Effects: Constructs an empty set using the specified comparison objects and allocator.
Complexity: Constant.
template<class InputIterator> set(InputIterator first, InputIterator last, const Compare& comp = Compare(), const Allocator& = Allocator());
Effects: Constructs an empty set using the specified comparison object and allocator, and inserts elements from the range [first, last).
Complexity: Linear in N if the range [first, last) is already sorted using comp and otherwise , where N is last - first.
