In which scenario would you prefer using an AVL tree over a Red-Black tree?
When frequent insertions and deletions are required.
When search operations are more frequent than insertions.
When memory usage is a concern.
When the tree needs to be unbalanced.
AVL trees provide faster lookups than Red-Black trees, making them preferable when search operations are more frequent.

Q: In which scenario would you prefer using an AVL tree over a Red-Black tree?
Solution: AVL trees provide faster lookups than Red-Black trees, making them preferable when search operations are more frequent.
Steps: 5
Step 1: Understand what an AVL tree is. It is a type of self-balancing binary search tree where the difference in heights between the left and right subtrees is at most 1.
Step 2: Understand what a Red-Black tree is. It is another type of self-balancing binary search tree that allows for a bit more flexibility in balancing, which can lead to faster insertions and deletions.
Step 3: Compare the performance of AVL trees and Red-Black trees. AVL trees are generally faster for search operations because they are more strictly balanced.
Step 4: Identify scenarios where search operations are more frequent than insertions or deletions. For example, if you have a database that mostly retrieves data and rarely updates it.
Step 5: Conclude that in scenarios with frequent search operations, you would prefer using an AVL tree over a Red-Black tree due to its faster lookup times.
