How do skip lists compare to other data structures?

How do skip lists compare to balanced trees?

Skip lists offer average-case O(log n) time complexity for search, insert, and delete operations, similar to balanced trees. However, they are simpler to implement and can be more efficient in practice for certain applications.

What are the advantages of using skip lists?

Some advantages of skip lists include their simplicity, ease of implementation, and good average-case performance. They also allow for fast search, insertion, and deletion operations.

Are there any downsides to using skip lists?

Yes, skip lists can have higher memory overhead due to the multiple pointers for each element. Additionally, their performance can degrade in the worst case, unlike balanced trees which guarantee O(log n) time.

In what scenarios would you recommend using skip lists?

Skip lists are great for applications requiring dynamic data structures with frequent insertions and deletions, such as in databases or memory management systems.
