If I have, for instance 5 nodes containing the variables 1, 2, 3, 4, 5, how can I link the nodes in order to obtain 3, 2, 1, 4, 5 ? (Change the first node with the third one, and the third with the first). Thanks.

Remove the node with key==1 and insert it after node 2. Then remove node 3 and put it at the head of the list. (By “node 3”, I mean the node with key == 3, not the node that is third in the list, which is now the node with key == 1.)
