list (i.e. p.info=12):
(head) 7 1 6 4 3 12 8 21 (tail)
What does the list look like after the following java code snippet is run?
int x = 13;
Node f = p.prev; //prev is a link to predecessor node
Node q = new Node(x);q.prev = f; q.next = p;
f.next q; p.prev = q;
A. 7 1 6 4 3 12 8 21 13
Β. 7 1 6 4 3 13 12 8 21
C. 7 1 6 4 3 12 13 8 21
D. 7 13 1 6 4 3 12 8 21
