When multiple ownership is needed, `Rc`(Reference Counting) can be used. `Rc` keeps track of the number of the references which means the number of owners of the value wrapped inside an `Rc`.

Reference count of an `Rc` increases by 1 whenever an `Rc` is cloned, and decreases by 1 whenever one cloned `Rc` is dropped out of the scope. When an `Rc`'s reference count becomes zero, which means there are no owners remained, both the `Rc` and the value are all dropped.

Cloning an `Rc` never performs a deep copy. Cloning creates just another pointer to the wrapped value, and increments the count.
