Deleting the Node Following a Given Node

Algorithm: DEL(INFO,  LINK,  START,  AVAIL,  LOC,  LOCP)

This algorithm deletes the node N with location LOC,  LOCP is the location of the node which precedes N or , where N is the first node,  LOCP = NULL.

1.   If LOCP = NULL, then:

    Set START : = LINK[START].     [Deletes first node]

Else: 

       Set LINK[LOCP]  : = LINK[LOC].    [Delete node N.]

[End of structure .]

2.      [Return  deleted node to the AVAIL list.]

     Set LINK[LOC]  : = AVAIL and AVAIL : = LOC

3.  Exit
