Create a class using C++ called LinkedList that represents a doubly linked list. Code the following functions for the class, according to their descriptions.

	LinkedList ()
	Default constructor. Constructs an empty list.
	LinkedList (std::initializer_list< T > init_list)
	Constructs a list with a copy of each of the elements in init_list, in the same order. More...
	LinkedList (const LinkedList &another)
	Constructs a container with a copy of each of the elements in another, in the same order. More...
	~LinkedList ()
	Destroys each of the contained elements, and deallocates all memory allocated by this list.
std::size_t	Size () const
	Returns the number of elements in this list. More...
bool	IsEmpty () const
	Returns whether the list container is empty (i.e. whether its size is 0). More...
T &	Front () const
	Returns a reference to the value in the first element in this list. More...
T &	Back () const
	Returns a reference to the value in the last element in this list. More...
void	PushBack (T val)
	Appends a new element to this list, after its current last element. More...
void	PushFront (T val)
	Prepends a new element to this list, before its current first element. More...
void	PopFront ()
	Deletes the first value in this list. More...
void	PopBack ()
	Deletes the last value in this list. More...
void	Resize (std::size_t n, const T &fill_value)
	Resizes the list so that it contains n elements. More...
void	Clear ()
	Deletes all values in this list.
void	Remove (const T &val)
	Removes from the container all the elements that compare equal to val. More...
void	Unique ()
	Removes duplicate values from this list. More...
void	Reverse ()
	Reverses the order of the elements in this list. More...
LinkedList &	operator= (std::initializer_list< T > init_list)
	Replaces the contents of this list with a copy of each element in init_list, in the same order. More...
LinkedList &	operator= (const LinkedList &another)
	Replaces the contents of this list with a copy of each element in another, in the same order. More...
bool	operator== (const LinkedList &another)
	Compares this list with another for equality. More...
bool	operator!= (const LinkedList &another)
	Compares this list with another for inequality. More...
