Given that a linked chain exists in memory as represented by the following:

firstNode "A" "B" "C" "D" "E"

Consider execution of the following code, upon the linked chain above. What is the resulting order of Nodes?

Node p = firstNode;

Node q = firstNode;

Node r = firstNode;

while( r.next != null ) {

p = q; q = r; r = r.next;

}

p.next = r;

q.next = null;

r.next = q;
