An XOR linked list is a more memory efficient doubly linked list. Instead of each node holding next and prev fields, it holds a field named both ,which is an XOR of the next node and the previous node. Implement an XOR linked list; it has an add(element) which adds the element to the end, and a get(index) which returns the node at index. If using a language that has no pointers (such as Python), you can assume you have access to get_pointer and dereference_pointer functions that converts between nodes and memory addresses.

An XOR linked list is a more
memory efficient doubly linked
list. Instead of each node holding
next and prev fields, it holds
a field named both,which is an
XOR of the next node and the
previous node. Implement an
XOR linked list; it has an
add(element) which adds the
element to the end, and a
get(index) which returns the
node at index.
If using a language that has no
pointers (such as Python), you
can assume you have access to
get_pointer and
dereference_pointer
functions that converts between
nodes and memory addresses.
