Problem $2.$ The templated class UnsortedList based on linked nodes is given below. Write the prototype and definition of member function splitList which divides the current list into two lists according to a given key. The precondition and postcondition of a new member function splitList are below:

$//$ Precondition: the current list has been initialized.

$//$ Postcondition: listl contains all elements of the current list which are less than or equal to the given key. The second list $2$ contains data which are greater than the given key.
