Chapter 19, Problem 5FTE
Explanation of Solution
Purpose of the given code:
The given code is used to remove the last node from a nonempty doubly linked list “myList”.
Given code:
/* The reference last points to the last node in a nonempty doubly linked list. Remove the last node from the list */
last = last.prev;
Error in the given code:
First, user needs to check if the list is nonempty, and also have to undo the removed node, and then set the next reference of the new last node to null.
/* If the last node is equal to "null", then */
if (last == null)
/* Set "first" to "null" */
first = null;
//Otherwise
else
{
/* Set the reference "prev" of last node to "null" */
last.next.prev = null;
/* Set next node of last to "null" */
last.next = null;
}
Corrected code:
/* The reference last points to the last node in a nonempty doubly linked list...
