Consider a linked list of items that are in no particular order.
 
a. Write instructions to insert a node at the beginning of the linked list. Assume the linked list has only a head reference.
b. Write instructions to delete a node at the beginning of the linked list. Assume the linked list has only a head reference.
 
c. Write instructions to insert a node at the end of the linked list. Assume the linked list has only a head reference.
 
d. Write instructions to delete a node at the end of the linked list. Assume the linked list has only a head reference.
 
e. Write instructions to insert a node at the end of the linked list. Assume the linked list has a head reference and a tail reference.
 
f. Write instructions to delete a node at the end of the linked list.
Assume the linked list has a head reference and a tail reference.
 
Note that you may need to consider special cases. For example, inset into an empty
linked list or remove from a linked list with one node. The first step to solve this problem should be to identify all possible cases.
