Advanced lists
We have already talked about lists in the previous chapter as node-based data structures. Knowing how lists work, it may be interesting for us to dive deeper into the data structure to understand what other variations it has. In this part of the chapter, we are going to find out whether lists can be any better or not and what other variations of lists there are.
Among the list variations are skip lists, XOR lists, unrolled lists, self-organizing lists, and so on. We are not going to talk about every advanced list type there is, but only one or two to make the idea of an advanced data structure, specifically an advanced list data structure, clearer.
Skip lists
The name “skip list” hints that the data structure should be connected with skipping something. The only thing it can skip is a node, as it is composed of nodes. This means that in some operations that are performed on lists, we can skip the accepted steps. Let us take for example the search...
