You have to implement and test a doubly linked list class. Save the header and implementation files separately.

$$ Begin by creating a template class NodeT that represents each node in the doubly linked list. This class should have:

o public data members: item $($template type attribute$),$ next and prev $($both pointers$).$

o public methods: The class should have two constructors $-$ one default that sets both the pointers to the nullptr and one with three parameters that sets the item, next and prev to the parameter values.
