Q:

Linked lists and references

list-->[-1-]<-->[-2-]<-->[-3-]<-->[-4-]<-->[-5-]
The above diagram is a circular doubly linked list of 5 nodes, and "list" is a reference/pointer to the first node.The last node, 5, and the fist node, 1, reference one another, as this list is circular, but I couldn't depict that diagrammatically. 
Does the assignment
list.next.next.next =list.prev 
on the above list modify it into the list
list-->[-1-]<-->[-2-]<-->[-3-]<-->[-5-]?
EDIT:
This isn't homework. I'm going over exercises in a textbook for self study. The book doesn't provide answers, so I decided to ask here. 

A:

as it is double linked, to create an other, valid, doubly-linked list, you have to update at least one next and one prev link (in the general case). as you update only one next link, it can not create what you show, as this is a valid example.
3.next would be 5, but 5.prev would still be 4.
