Question

What is the difference between singly linked lists and doubly linked lists?

a.

Singly linked lists have only a "next" pointer, while doubly linked lists have both a "next" pointer and a "previous" pointer.

b.

Singly linked lists have only a "previous" pointer, while doubly linked lists have both a "next" pointer and a "previous" pointer.

c.

Singly linked lists have only a "next" pointer, while doubly linked lists have only a "previous" pointer.

d.
