...node is empty? Basically, lets say you have a linked list of 10 elements where they look something like:

listA.add(1);
listA.add(2);
listA.add(3);
listA.add(null);
listA.add(5);
listA.add(6);
listA.add(7);
listA.add(8);
listA.add(9);

therefore contains 10 elements, but the 4th element contains a null value. What is the most EFFICIENT way to find the node that contains the null value without iterating through the whole linked list?

Info: Linked list is not necessarily sorted, and even though the node contains a null value, it still exists therefore its still pointing to the next item in the list.

Thanks
