What is the memory usage of skip lists in C++?

What is the memory usage of skip lists in C++?

Skip lists use O(n) memory, where n is the number of elements, due to multiple pointers for each element.

How does the memory usage compare to balanced trees?

Balanced trees also use O(n) memory, but they may have a lower constant factor compared to skip lists.

Are there any optimizations for reducing memory usage in skip lists?

Yes, you can optimize by reducing the number of levels or using a more compact representation for pointers.

What are the advantages of using skip lists despite the memory usage?

Skip lists offer fast search, insert, and delete operations, often outperforming balanced trees in practice.
