What are the different variations of binary search trees?

There are several variations of binary search trees, including AVL trees, Red-Black trees, Splay trees, and Treaps. Each has unique properties and use cases.

Can you explain how AVL trees differ from Red-Black trees?

Sure! AVL trees maintain a stricter balance than Red-Black trees, ensuring that the heights of the two child subtrees of any node differ by at most one. This leads to faster lookups but can result in more rotations during insertions and deletions.

What are Splay trees used for?

Splay trees are used for scenarios where certain elements are accessed more frequently than others. They perform a self-adjusting operation that moves accessed elements closer to the root, optimizing future access.

Are there any practical applications for Treaps?

Yes, Treaps are used in applications that require both priority and order, such as in randomized algorithms and in maintaining a dynamic set of ordered elements.
